1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. See end of file for further details. For commonly 5done items, please see the COMMON ITEMS: section later in the file. 6 7Items affecting the ports and packages system can be found in 8/usr/ports/UPDATING. Please read that file before running 9portupgrade. 10 11NOTE TO PEOPLE WHO THINK THAT FreeBSD 8.x IS SLOW: 12 FreeBSD 8.x has many debugging features turned on, in 13 both the kernel and userland. These features attempt to detect 14 incorrect use of system primitives, and encourage loud failure 15 through extra sanity checking and fail stop semantics. They 16 also substantially impact system performance. If you want to 17 do performance measurement, benchmarking, and optimization, 18 you'll want to turn them off. This includes various WITNESS- 19 related kernel options, INVARIANTS, malloc debugging flags 20 in userland, and various verbose features in the kernel. Many 21 developers choose to disable these features on build machines 22 to maximize performance. (To disable malloc debugging, run 23 ln -s aj /etc/malloc.conf.) 24 2520090223: 26 The new USB2 stack has now been permanently moved in and all kernel and 27 module names reverted to their previous values (eg, usb, ehci, ohci, 28 ums, ...). The old usb stack can be compiled in by prefixing the name 29 with the letter 'o', the old usb modules have been removed. 30 Updating entry 20090216 for xorg may still apply. 31 3220090217: 33 The rc.conf(5) option if_up_delay has been renamed to 34 defaultroute_delay to better reflect its purpose. If you have 35 customized this setting in /etc/rc.conf you need to update it to 36 use the new name. 37 3820090216: 39 xorg 7.4 wants to configure its input devices via hald which does not 40 yet work with USB2. If the keyboard/mouse does not work in xorg then 41 add 42 Option "AllowEmptyInput" "off" 43 to your ServerLayout section. This will cause X to use the configured 44 kbd and mouse sections from your xorg.conf. 45 4620090215: 47 The GENERIC kernels for all architectures now default to the new USB2 48 stack. No kernel config options or code have been removed so if a 49 problem arises please report it and optionally revert to the old USB 50 stack. If you are loading USB kernel modules or have a custom kernel 51 that includes GENERIC then ensure that usb names are also changed over, 52 eg uftdi -> usb2_serial_ftdi. 53 5420090203: 55 The ichsmb(4) driver has been changed to require SMBus slave 56 addresses be left-justified (xxxxxxx0b) rather than right-justified. 57 All of the other SMBus controller drivers require left-justified 58 slave addresses, so this change makes all the drivers provide the 59 same interface. 60 6120090201: 62 INET6 statistics (struct ip6stat) was updated. 63 netstat(1) needs to be recompiled. 64 6520090119: 66 NTFS has been removed from GENERIC kernel on amd64 to match 67 GENERIC on i386. Should not cause any issues since mount_ntfs(8) 68 will load ntfs.ko module automatically when NTFS support is 69 actually needed, unless ntfs.ko is not installed or security 70 level prohibits loading kernel modules. If either is the case, 71 "options NTFS" has to be added into kernel config. 72 7320090115: 74 TCP Appropriate Byte Counting (RFC 3465) support added to kernel. 75 New field in struct tcpcb breaks ABI, so bump __FreeBSD_version to 76 800061. User space tools that rely on the size of struct tcpcb in 77 tcp_var.h (e.g. sockstat) need to be recompiled. 78 7920081225: 80 ng_tty(4) module updated to match the new TTY subsystem. 81 Due to API change, user-level applications must be updated. 82 New API support added to mpd5 CVS and expected to be present 83 in next mpd5.3 release. 84 8520081219: 86 With __FreeBSD_version 800060 the makefs tool is part of 87 the base system (it was a port). 88 8920081216: 90 The afdata and ifnet locks have been changed from mutexes to 91 rwlocks, network modules will need to be re-compiled. 92 9320081214: 94 __FreeBSD_version 800059 incorporates the new arp-v2 rewrite. 95 RTF_CLONING, RTF_LLINFO and RTF_WASCLONED flags are eliminated. 96 The new code reduced struct rtentry{} by 16 bytes on 32-bit 97 architecture and 40 bytes on 64-bit architecture. The userland 98 applications "arp" and "ndp" have been updated accordingly. 99 The output from "netstat -r" shows only routing entries and 100 none of the L2 information. 101 10220081130: 103 __FreeBSD_version 800057 marks the switchover from the 104 binary ath hal to source code. Users must add the line: 105 106 options AH_SUPPORT_AR5416 107 108 to their kernel config files when specifying: 109 110 device ath_hal 111 112 The ath_hal module no longer exists; the code is now compiled 113 together with the driver in the ath module. It is now 114 possible to tailor chip support (i.e. reduce the set of chips 115 and thereby the code size); consult ath_hal(4) for details. 116 11720081121: 118 __FreeBSD_version 800054 adds memory barriers to 119 <machine/atomic.h>, new interfaces to ifnet to facilitate 120 multiple hardware transmit queues for cards that support 121 them, and a lock-less ring-buffer implementation to 122 enable drivers to more efficiently manage queueing of 123 packets. 124 12520081117: 126 A new version of ZFS (version 13) has been merged to -HEAD. 127 This version has zpool attribute "listsnapshots" off by 128 default, which means "zfs list" does not show snapshots, 129 and is the same as Solaris behavior. 130 13120081028: 132 dummynet(4) ABI has changed. ipfw(8) needs to be recompiled. 133 13420081009: 135 The uhci, ohci, ehci and slhci USB Host controller drivers have 136 been put into separate modules. If you load the usb module 137 separately through loader.conf you will need to load the 138 appropriate *hci module as well. E.g. for a UHCI-based USB 2.0 139 controller add the following to loader.conf: 140 141 uhci_load="YES" 142 ehci_load="YES" 143 14420081009: 145 The ABI used by the PMC toolset has changed. Please keep 146 userland (libpmc(3)) and the kernel module (hwpmc(4)) in 147 sync. 148 14920080820: 150 The TTY subsystem of the kernel has been replaced by a new 151 implementation, which provides better scalability and an 152 improved driver model. Most common drivers have been migrated to 153 the new TTY subsystem, while others have not. The following 154 drivers have not yet been ported to the new TTY layer: 155 156 PCI/ISA: 157 cy, digi, rc, rp, sio 158 159 USB: 160 ubser, ucycom 161 162 Line disciplines: 163 ng_h4, ng_tty, ppp, sl, snp 164 165 Adding these drivers to your kernel configuration file shall 166 cause compilation to fail. 167 16820080818: 169 ntpd has been upgraded to 4.2.4p5. 170 17120080801: 172 OpenSSH has been upgraded to 5.1p1. 173 174 For many years, FreeBSD's version of OpenSSH preferred DSA 175 over RSA for host and user authentication keys. With this 176 upgrade, we've switched to the vendor's default of RSA over 177 DSA. This may cause upgraded clients to warn about unknown 178 host keys even for previously known hosts. Users should 179 follow the usual procedure for verifying host keys before 180 accepting the RSA key. 181 182 This can be circumvented by setting the "HostKeyAlgorithms" 183 option to "ssh-dss,ssh-rsa" in ~/.ssh/config or on the ssh 184 command line. 185 186 Please note that the sequence of keys offered for 187 authentication has been changed as well. You may want to 188 specify IdentityFile in a different order to revert this 189 behavior. 190 19120080713: 192 The sio(4) driver has been removed from the i386 and amd64 193 kernel configuration files. This means uart(4) is now the 194 default serial port driver on those platforms as well. 195 196 To prevent collisions with the sio(4) driver, the uart(4) driver 197 uses different names for its device nodes. This means the 198 onboard serial port will now most likely be called "ttyu0" 199 instead of "ttyd0". You may need to reconfigure applications to 200 use the new device names. 201 202 When using the serial port as a boot console, be sure to update 203 /boot/device.hints and /etc/ttys before booting the new kernel. 204 If you forget to do so, you can still manually specify the hints 205 at the loader prompt: 206 207 set hint.uart.0.at="isa" 208 set hint.uart.0.port="0x3F8" 209 set hint.uart.0.flags="0x10" 210 set hint.uart.0.irq="4" 211 boot -s 212 21320080609: 214 The gpt(8) utility has been removed. Use gpart(8) to partition 215 disks instead. 216 21720080603: 218 The version that Linuxulator emulates was changed from 2.4.2 219 to 2.6.16. If you experience any problems with Linux binaries 220 please try to set sysctl compat.linux.osrelease to 2.4.2 and 221 if it fixes the problem contact emulation mailing list. 222 22320080525: 224 ISDN4BSD (I4B) was removed from the src tree. You may need to 225 update a your kernel configuration and remove relevant entries. 226 22720080509: 228 I have checked in code to support multiple routing tables. 229 See the man pages setfib(1) and setfib(2). 230 This is a hopefully backwards compatible version, 231 but to make use of it you need to compile your kernel 232 with options ROUTETABLES=2 (or more up to 16). 233 23420080420: 235 The 802.11 wireless support was redone to enable multi-bss 236 operation on devices that are capable. The underlying device 237 is no longer used directly but instead wlanX devices are 238 cloned with ifconfig. This requires changes to rc.conf files. 239 For example, change: 240 ifconfig_ath0="WPA DHCP" 241 to 242 wlans_ath0=wlan0 243 ifconfig_wlan0="WPA DHCP" 244 see rc.conf(5) for more details. In addition, mergemaster of 245 /etc/rc.d is highly recommended. Simultaneous update of userland 246 and kernel wouldn't hurt either. 247 248 As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta 249 modules were merged into the base wlan module. All references 250 to these modules (e.g. in kernel config files) must be removed. 251 25220080408: 253 psm(4) has gained write(2) support in native operation level. 254 Arbitrary commands can be written to /dev/psm%d and status can 255 be read back from it. Therefore, an application is responsible 256 for status validation and error recovery. It is a no-op in 257 other operation levels. 258 25920080312: 260 Support for KSE threading has been removed from the kernel. To 261 run legacy applications linked against KSE libmap.conf may 262 be used. The following libmap.conf may be used to ensure 263 compatibility with any prior release: 264 265 libpthread.so.1 libthr.so.1 266 libpthread.so.2 libthr.so.2 267 libkse.so.3 libthr.so.3 268 26920080301: 270 The layout of struct vmspace has changed. This affects libkvm 271 and any executables that link against libkvm and use the 272 kvm_getprocs() function. In particular, but not exclusively, 273 it affects ps(1), fstat(1), pkill(1), systat(1), top(1) and w(1). 274 The effects are minimal, but it's advisable to upgrade world 275 nonetheless. 276 27720080229: 278 The latest em driver no longer has support in it for the 279 82575 adapter, this is now moved to the igb driver. The 280 split was done to make new features that are incompatible 281 with older hardware easier to do. 282 28320080220: 284 The new geom_lvm(4) geom class has been renamed to geom_linux_lvm(4), 285 likewise the kernel option is now GEOM_LINUX_LVM. 286 28720080211: 288 The default NFS mount mode has changed from UDP to TCP for 289 increased reliability. If you rely on (insecurely) NFS 290 mounting across a firewall you may need to update your 291 firewall rules. 292 29320080208: 294 Belatedly note the addition of m_collapse for compacting 295 mbuf chains. 296 29720080126: 298 The fts(3) structures have been changed to use adequate 299 integer types for their members and so to be able to cope 300 with huge file trees. The old fts(3) ABI is preserved 301 through symbol versioning in libc, so third-party binaries 302 using fts(3) should still work, although they will not take 303 advantage of the extended types. At the same time, some 304 third-party software might fail to build after this change 305 due to unportable assumptions made in its source code about 306 fts(3) structure members. Such software should be fixed 307 by its vendor or, in the worst case, in the ports tree. 308 FreeBSD_version 800015 marks this change for the unlikely 309 case that a portable fix is impossible. 310 31120080123: 312 To upgrade to -current after this date, you must be running 313 FreeBSD not older than 6.0-RELEASE. Upgrading to -current 314 from 5.x now requires a stop over at RELENG_6 or RELENG_7 systems. 315 31620071128: 317 The ADAPTIVE_GIANT kernel option has been retired because its 318 functionality is the default now. 319 32020071118: 321 The AT keyboard emulation of sunkbd(4) has been turned on 322 by default. In order to make the special symbols of the Sun 323 keyboards driven by sunkbd(4) work under X these now have 324 to be configured the same way as Sun USB keyboards driven 325 by ukbd(4) (which also does AT keyboard emulation), f.e.: 326 327 Option "XkbLayout" "us" 328 Option "XkbRules" "xorg" 329 Option "XkbSymbols" "pc(pc105)+sun_vndr/usb(sun_usb)+us" 330 33120071024: 332 It has been decided that it is desirable to provide ABI 333 backwards compatibility to the FreeBSD 4/5/6 versions of the 334 PCIOCGETCONF, PCIOCREAD and PCIOCWRITE IOCTLs, which was 335 broken with the introduction of PCI domain support (see the 336 20070930 entry). Unfortunately, this required the ABI of 337 PCIOCGETCONF to be broken again in order to be able to 338 provide backwards compatibility to the old version of that 339 IOCTL. Thus consumers of PCIOCGETCONF have to be recompiled 340 again. As for prominent ports this affects neither pciutils 341 nor xorg-server this time, the hal port needs to be rebuilt 342 however. 343 34420071020: 345 The misnamed kthread_create() and friends have been renamed 346 to kproc_create() etc. Many of the callers already 347 used kproc_start().. 348 I will return kthread_create() and friends in a while 349 with implementations that actually create threads, not procs. 350 Renaming corresponds with version 800002. 351 35220071010: 353 RELENG_7 branched. 354 35520071009: 356 Setting WITHOUT_LIBPTHREAD now means WITHOUT_LIBKSE and 357 WITHOUT_LIBTHR are set. 358 35920070930: 360 The PCI code has been made aware of PCI domains. This means that 361 the location strings as used by pciconf(8) etc are now in the 362 following format: pci<domain>:<bus>:<device>[:<function>]. It 363 also means that consumers of <sys/pciio.h> potentially need to 364 be recompiled; this includes the hal and xorg-server ports. 365 36620070928: 367 The caching daemon (cached) was renamed to nscd. nscd.conf 368 configuration file should be used instead of cached.conf and 369 nscd_enable, nscd_pidfile and nscd_flags options should be used 370 instead of cached_enable, cached_pidfile and cached_flags in 371 rc.conf. 372 37320070921: 374 The getfacl(1) utility now prints owning user and group name 375 instead of owning uid and gid in the three line comment header. 376 This is the same behavior as getfacl(1) on Solaris and Linux. 377 37820070704: 379 The new IPsec code is now compiled in using the IPSEC option. The 380 IPSEC option now requires "device crypto" be defined in your kernel 381 configuration. The FAST_IPSEC kernel option is now deprecated. 382 38320070702: 384 The packet filter (pf) code has been updated to OpenBSD 4.1 Please 385 note the changed syntax - keep state is now on by default. Also 386 note the fact that ftp-proxy(8) has been changed from bottom up and 387 has been moved from libexec to usr/sbin. Changes in the ALTQ 388 handling also affect users of IPFW's ALTQ capabilities. 389 39020070701: 391 Remove KAME IPsec in favor of FAST_IPSEC, which is now the 392 only IPsec supported by FreeBSD. The new IPsec stack 393 supports both IPv4 and IPv6. The kernel option will change 394 after the code changes have settled in. For now the kernel 395 option IPSEC is deprecated and FAST_IPSEC is the only option, that 396 will change after some settling time. 397 39820070701: 399 The wicontrol(8) utility has been removed from the base system. wi(4) 400 cards should be configured using ifconfig(8), see the man page for more 401 information. 402 40320070612: 404 The i386/amd64 GENERIC kernel now defaults to the nfe(4) driver 405 instead of the nve(4) driver. Please update your configuration 406 accordingly. 407 40820070612: 409 By default, /etc/rc.d/sendmail no longer rebuilds the aliases 410 database if it is missing or older than the aliases file. If 411 desired, set the new rc.conf option sendmail_rebuild_aliases 412 to "YES" to restore that functionality. 413 41420070612: 415 The IPv4 multicast socket code has been considerably modified, and 416 moved to the file sys/netinet/in_mcast.c. Initial support for the 417 RFC 3678 Source-Specific Multicast Socket API has been added to 418 the IPv4 network stack. 419 420 Strict multicast and broadcast reception is now the default for 421 UDP/IPv4 sockets; the net.inet.udp.strict_mcast_mship sysctl variable 422 has now been removed. 423 424 The RFC 1724 hack for interface selection has been removed; the use 425 of the Linux-derived ip_mreqn structure with IP_MULTICAST_IF has 426 been added to replace it. Consumers such as routed will soon be 427 updated to reflect this. 428 429 These changes affect users who are running routed(8) or rdisc(8) 430 from the FreeBSD base system on point-to-point or unnumbered 431 interfaces. 432 43320070610: 434 The net80211 layer has changed significantly and all wireless 435 drivers that depend on it need to be recompiled. Further these 436 changes require that any program that interacts with the wireless 437 support in the kernel be recompiled; this includes: ifconfig, 438 wpa_supplicant, hostapd, and wlanstats. Users must also, for 439 the moment, kldload the wlan_scan_sta and/or wlan_scan_ap modules 440 if they use modules for wireless support. These modules implement 441 scanning support for station and ap modes, respectively. Failure 442 to load the appropriate module before marking a wireless interface 443 up will result in a message to the console and the device not 444 operating properly. 445 44620070610: 447 The pam_nologin(8) module ceases to provide an authentication 448 function and starts providing an account management function. 449 Consequent changes to /etc/pam.d should be brought in using 450 mergemaster(8). Third-party files in /usr/local/etc/pam.d may 451 need manual editing as follows. Locate this line (or similar): 452 453 auth required pam_nologin.so no_warn 454 455 and change it according to this example: 456 457 account required pam_nologin.so no_warn 458 459 That is, the first word needs to be changed from "auth" to 460 "account". The new line can be moved to the account section 461 within the file for clarity. Not updating pam.conf(5) files 462 will result in nologin(5) ignored by the respective services. 463 46420070529: 465 The ether_ioctl() function has been synchronized with ioctl(2) 466 and ifnet.if_ioctl. Due to that, the size of one of its arguments 467 has changed on 64-bit architectures. All kernel modules using 468 ether_ioctl() need to be rebuilt on such architectures. 469 47020070516: 471 Improved INCLUDE_CONFIG_FILE support has been introduced to the 472 config(8) utility. In order to take advantage of this new 473 functionality, you are expected to recompile and install 474 src/usr.sbin/config. If you don't rebuild config(8), and your 475 kernel configuration depends on INCLUDE_CONFIG_FILE, the kernel 476 build will be broken because of a missing "kernconfstring" 477 symbol. 478 47920070513: 480 Symbol versioning is enabled by default. To disable it, use 481 option WITHOUT_SYMVER. It is not advisable to attempt to 482 disable symbol versioning once it is enabled; your installworld 483 will break because a symbol version-less libc will get installed 484 before the install tools. As a result, the old install tools, 485 which previously had symbol dependencies to FBSD_1.0, will fail 486 because the freshly installed libc will not have them. 487 488 The default threading library (providing "libpthread") has been 489 changed to libthr. If you wish to have libkse as your default, 490 use option DEFAULT_THREAD_LIB=libkse for the buildworld. 491 49220070423: 493 The ABI breakage in sendmail(8)'s libmilter has been repaired 494 so it is no longer necessary to recompile mail filters (aka, 495 milters). If you recompiled mail filters after the 20070408 496 note, it is not necessary to recompile them again. 497 49820070417: 499 The new trunk(4) driver has been renamed to lagg(4) as it better 500 reflects its purpose. ifconfig will need to be recompiled. 501 50220070408: 503 sendmail(8) has been updated to version 8.14.1. Mail filters 504 (aka, milters) compiled against the libmilter included in the 505 base operating system should be recompiled. 506 50720070302: 508 Firmwares for ipw(4) and iwi(4) are now included in the base tree. 509 In order to use them one must agree to the respective LICENSE in 510 share/doc/legal and define legal.intel_<name>.license_ack=1 via 511 loader.conf(5) or kenv(1). Make sure to deinstall the now 512 deprecated modules from the respective firmware ports. 513 51420070228: 515 The name resolution/mapping functions addr2ascii(3) and ascii2addr(3) 516 were removed from FreeBSD's libc. These originally came from INRIA 517 IPv6. Nothing in FreeBSD ever used them. They may be regarded as 518 deprecated in previous releases. 519 The AF_LINK support for getnameinfo(3) was merged from NetBSD to 520 replace it as a more portable (and re-entrant) API. 521 52220070224: 523 To support interrupt filtering a modification to the newbus API 524 has occurred, ABI was broken and __FreeBSD_version was bumped 525 to 700031. Please make sure that your kernel and modules are in 526 sync. For more info: 527 http://docs.freebsd.org/cgi/mid.cgi?20070221233124.GA13941 528 52920070224: 530 The IPv6 multicast forwarding code may now be loaded into GENERIC 531 kernels by loading the ip_mroute.ko module. This is built into the 532 module unless WITHOUT_INET6 or WITHOUT_INET6_SUPPORT options are 533 set; see src.conf(5) for more information. 534 53520070214: 536 The output of netstat -r has changed. Without -n, we now only 537 print a "network name" without the prefix length if the network 538 address and mask exactly match a Class A/B/C network, and an entry 539 exists in the nsswitch "networks" map. 540 With -n, we print the full unabbreviated CIDR network prefix in 541 the form "a.b.c.d/p". 0.0.0.0/0 is always printed as "default". 542 This change is in preparation for changes such as equal-cost 543 multipath, and to more generally assist operational deployment 544 of FreeBSD as a modern IPv4 router. 545 54620070210: 547 PIM has been turned on by default in the IPv4 multicast 548 routing code. The kernel option 'PIM' has now been removed. 549 PIM is now built by default if option 'MROUTING' is specified. 550 It may now be loaded into GENERIC kernels by loading the 551 ip_mroute.ko module. 552 55320070207: 554 Support for IPIP tunnels (VIFF_TUNNEL) in IPv4 multicast routing 555 has been removed. Its functionality may be achieved by explicitly 556 configuring gif(4) interfaces and using the 'phyint' keyword in 557 mrouted.conf. 558 XORP does not support source-routed IPv4 multicast tunnels nor the 559 integrated IPIP tunneling, therefore it is not affected by this 560 change. The __FreeBSD_version macro has been bumped to 700030. 561 56220061221: 563 Support for PCI Message Signalled Interrupts has been 564 re-enabled in the bge driver, only for those chips which are 565 believed to support it properly. If there are any problems, 566 MSI can be disabled completely by setting the 567 'hw.pci.enable_msi' and 'hw.pci.enable_msix' tunables to 0 568 in the loader. 569 57020061214: 571 Support for PCI Message Signalled Interrupts has been 572 disabled again in the bge driver. Many revisions of the 573 hardware fail to support it properly. Support can be 574 re-enabled by removing the #define of BGE_DISABLE_MSI in 575 "src/sys/dev/bge/if_bge.c". 576 57720061214: 578 Support for PCI Message Signalled Interrupts has been added 579 to the bge driver. If there are any problems, MSI can be 580 disabled completely by setting the 'hw.pci.enable_msi' and 581 'hw.pci.enable_msix' tunables to 0 in the loader. 582 58320061205: 584 The removal of several facets of the experimental Threading 585 system from the kernel means that the proc and thread structures 586 have changed quite a bit. I suggest all kernel modules that might 587 reference these structures be recompiled.. Especially the 588 linux module. 589 59020061126: 591 Sound infrastructure has been updated with various fixes and 592 improvements. Most of the changes are pretty much transparent, 593 with exceptions of followings: 594 1) All sound driver specific sysctls (hw.snd.pcm%d.*) have been 595 moved to their own dev sysctl nodes, for example: 596 hw.snd.pcm0.vchans -> dev.pcm.0.vchans 597 2) /dev/dspr%d.%d has been deprecated. Each channel now has its 598 own chardev in the form of "dsp%d.<function>%d", where <function> 599 is p = playback, r = record and v = virtual, respectively. Users 600 are encouraged to use these devs instead of (old) "/dev/dsp%d.%d". 601 This does not affect those who are using "/dev/dsp". 602 60320061122: 604 geom(4)'s gmirror(8) class metadata structure has been 605 rev'd from v3 to v4. If you update across this point and 606 your metadata is converted for you, you will not be easily 607 able to downgrade since the /boot/kernel.old/geom_mirror.ko 608 kernel module will be unable to read the v4 metadata. You 609 can resolve this by doing from the loader(8) prompt: 610 611 set vfs.root.mountfrom="ufs:/dev/XXX" 612 613 where XXX is the root slice of one of the disks that composed 614 the mirror (i.e.: /dev/ad0s1a). You can then rebuild 615 the array the same way you built it originally. 616 61720061122: 618 The following binaries have been disconnected from the build: 619 mount_devfs, mount_ext2fs, mount_fdescfs, mount_procfs, mount_linprocfs, 620 and mount_std. The functionality of these programs has been 621 moved into the mount program. For example, to mount a devfs 622 filesystem, instead of using mount_devfs, use: "mount -t devfs". 623 This does not affect entries in /etc/fstab, since entries in 624 /etc/fstab are always processed with "mount -t fstype". 625 62620061113: 627 Support for PCI Message Signalled Interrupts on i386 and amd64 628 has been added to the kernel and various drivers will soon be 629 updated to use MSI when it is available. If there are any problems, 630 MSI can be disabled completely by setting the 'hw.pci.enable_msi' 631 and 'hw.pci.enable_msix' tunables to 0 in the loader. 632 63320061110: 634 The MUTEX_PROFILING option has been renamed to LOCK_PROFILING. 635 The lockmgr object layout has been changed as a result of having 636 a lock_object embedded in it. As a consequence all file system 637 kernel modules must be re-compiled. The mutex profiling man page 638 has not yet been updated to reflect this change. 639 64020061026: 641 KSE in the kernel has now been made optional and turned on by 642 default. Use 'nooption KSE' in your kernel config to turn it 643 off. All kernel modules *must* be recompiled after this change. 644 There-after, modules from a KSE kernel should be compatible with 645 modules from a NOKSE kernel due to the temporary padding fields 646 added to 'struct proc'. 647 64820060929: 649 mrouted and its utilities have been removed from the base system. 650 65120060927: 652 Some ioctl(2) command codes have changed. Full backward ABI 653 compatibility is provided if the "options COMPAT_FREEBSD6" is 654 present in the kernel configuration file. Make sure to add 655 this option to your kernel config file, or recompile X.Org 656 and the rest of ports; otherwise they may refuse to work. 657 65820060924: 659 tcpslice has been removed from the base system. 660 66120060913: 662 The sizes of struct tcpcb (and struct xtcpcb) have changed due to 663 the rewrite of TCP syncookies. Tools like netstat, sockstat, and 664 systat needs to be rebuilt. 665 66620060903: 667 libpcap updated to v0.9.4 and tcpdump to v3.9.4 668 66920060816: 670 The IPFIREWALL_FORWARD_EXTENDED option is gone and the behaviour 671 for IPFIREWALL_FORWARD is now as it was before when it was first 672 committed and for years after. The behaviour is now ON. 673 67420060725: 675 enigma(1)/crypt(1) utility has been changed on 64 bit architectures. 676 Now it can decrypt files created from different architectures. 677 Unfortunately, it is no longer able to decrypt a cipher text 678 generated with an older version on 64 bit architectures. 679 If you have such a file, you need old utility to decrypt it. 680 68120060709: 682 The interface version of the i4b kernel part has changed. So 683 after updating the kernel sources and compiling a new kernel, 684 the i4b user space tools in "/usr/src/usr.sbin/i4b" must also 685 be rebuilt, and vice versa. 686 68720060627: 688 The XBOX kernel now defaults to the nfe(4) driver instead of 689 the nve(4) driver. Please update your configuration 690 accordingly. 691 69220060514: 693 The i386-only lnc(4) driver for the AMD Am7900 LANCE and Am79C9xx 694 PCnet family of NICs has been removed. The new le(4) driver serves 695 as an equivalent but cross-platform replacement with the pcn(4) 696 driver still providing performance-optimized support for the subset 697 of AMD Am79C971 PCnet-FAST and greater chips as before. 698 69920060511: 700 The machdep.* sysctls and the adjkerntz utility have been 701 modified a bit. The new adjkerntz utility uses the new 702 sysctl names and sysctlbyname() calls, so it may be impossible 703 to run an old /sbin/adjkerntz utility in single-user mode 704 with a new kernel. Replace the `adjkerntz -i' step before 705 `make installworld' with: 706 707 /usr/obj/usr/src/sbin/adjkerntz/adjkerntz -i 708 709 and proceed as usual with the rest of the installworld-stage 710 steps. Otherwise, you risk installing binaries with their 711 timestamp set several hours in the future, especially if 712 you are running with local time set to GMT+X hours. 713 71420060412: 715 The ip6fw utility has been removed. The behavior provided by 716 ip6fw has been in ipfw2 for a good while and the rc.d scripts 717 have been updated to deal with it. There are some rules that 718 might not migrate cleanly. Use rc.firewall6 as a template to 719 rewrite rules. 720 72120060428: 722 The puc(4) driver has been overhauled. The ebus(4) and sbus(4) 723 attachments have been removed. Make sure to configure scc(4) 724 on sparc64. Note also that by default puc(4) will use uart(4) 725 and not sio(4) for serial ports because interrupt handling has 726 been optimized for multi-port serial cards and only uart(4) 727 implements the interface to support it. 728 72920060330: 730 The scc(4) driver replaces puc(4) for Serial Communications 731 Controllers (SCCs) like the Siemens SAB82532 and the Zilog 732 Z8530. On sparc64, it is advised to add scc(4) to the kernel 733 configuration to make sure that the serial ports remain 734 functional. 735 73620060317: 737 Most world/kernel related NO_* build options changed names. 738 New knobs have common prefixes WITHOUT_*/WITH_* (modelled 739 after FreeBSD ports) and should be set in /etc/src.conf 740 (the src.conf(5) manpage is provided). Full backwards 741 compatibility is maintained for the time being though it's 742 highly recommended to start moving old options out of the 743 system-wide /etc/make.conf file into the new /etc/src.conf 744 while also properly renaming them. More conversions will 745 likely follow. Posting to current@: 746 747 http://lists.freebsd.org/pipermail/freebsd-current/2006-March/061725.html 748 74920060305: 750 The NETSMBCRYPTO kernel option has been retired because its 751 functionality is always included in NETSMB and smbfs.ko now. 752 75320060303: 754 The TDFX_LINUX kernel option was retired and replaced by the 755 tdfx_linux device. The latter can be loaded as the 3dfx_linux.ko 756 kernel module. Loading it alone should suffice to get 3dfx support 757 for Linux apps because it will pull in 3dfx.ko and linux.ko through 758 its dependencies. 759 76020060204: 761 The 'audit' group was added to support the new auditing functionality 762 in the base system. Be sure to follow the directions for updating, 763 including the requirement to run mergemaster -p. 764 76520060201: 766 The kernel ABI to file system modules was changed on i386. 767 Please make sure that your kernel and modules are in sync. 768 76920060118: 770 This actually occured some time ago, but installing the kernel 771 now also installs a bunch of symbol files for the kernel modules. 772 This increases the size of /boot/kernel to about 67Mbytes. You 773 will need twice this if you will eventually back this up to kernel.old 774 on your next install. 775 If you have a shortage of room in your root partition, you should add 776 -DINSTALL_NODEBUG to your make arguments or add INSTALL_NODEBUG="yes" 777 to your /etc/make.conf. 778 77920060113: 780 libc's malloc implementation has been replaced. This change has the 781 potential to uncover application bugs that previously went unnoticed. 782 See the malloc(3) manual page for more details. 783 78420060112: 785 The generic netgraph(4) cookie has been changed. If you upgrade 786 kernel passing this point, you also need to upgrade userland 787 and netgraph(4) utilities like ports/net/mpd or ports/net/mpd4. 788 78920060106: 790 si(4)'s device files now contain the unit number. 791 Uses of {cua,tty}A[0-9a-f] should be replaced by {cua,tty}A0[0-9a-f]. 792 79320060106: 794 The kernel ABI was mostly destroyed due to a change in the size 795 of struct lock_object which is nested in other structures such 796 as mutexes which are nested in all sorts of other structures. 797 Make sure your kernel and modules are in sync. 798 79920051231: 800 The page coloring algorithm in the VM subsystem was converted 801 from tuning with kernel options to autotuning. Please remove 802 any PQ_* option except PQ_NOOPT from your kernel config. 803 80420051211: 805 The net80211-related tools in the tools/tools/ath directory 806 have been moved to tools/tools/net80211 and renamed with a 807 "wlan" prefix. Scripts that use them should be adjusted 808 accordingly. 809 81020051202: 811 Scripts in the local_startup directories (as defined in 812 /etc/defaults/rc.conf) that have the new rc.d semantics will 813 now be run as part of the base system rcorder. If there are 814 errors or problems with one of these local scripts, it could 815 cause boot problems. If you encounter such problems, boot in 816 single user mode, remove that script from the */rc.d directory. 817 Please report the problem to the port's maintainer, and the 818 freebsd-ports@freebsd.org mailing list. 819 82020051129: 821 The nodev mount option was deprecated in RELENG_6 (where it 822 was a no-op), and is now unsupported. If you have nodev or dev listed 823 in /etc/fstab, remove it, otherwise it will result in a mount error. 824 82520051129: 826 ABI between ipfw(4) and ipfw(8) has been changed. You need 827 to rebuild ipfw(8) when rebuilding kernel. 828 82920051108: 830 rp(4)'s device files now contain the unit number. 831 Uses of {cua,tty}R[0-9a-f] should be replaced by {cua,tty}R0[0-9a-f]. 832 83320051029: 834 /etc/rc.d/ppp-user has been renamed to /etc/rc.d/ppp. 835 Its /etc/rc.conf.d configuration file has been `ppp' from 836 the beginning, and hence there is no need to touch it. 837 83820051014: 839 Now most modules get their build-time options from the kernel 840 configuration file. A few modules still have fixed options 841 due to their non-conformant implementation, but they will be 842 corrected eventually. You may need to review the options of 843 the modules in use, explicitly specify the non-default options 844 in the kernel configuration file, and rebuild the kernel and 845 modules afterwards. 846 84720051001: 848 kern.polling.enable sysctl MIB is now deprecated. Use ifconfig(8) 849 to turn polling(4) on your interfaces. 850 85120050927: 852 The old bridge(4) implementation was retired. The new 853 if_bridge(4) serves as a full functional replacement. 854 85520050722: 856 The ai_addrlen of a struct addrinfo was changed to a socklen_t 857 to conform to POSIX-2001. This change broke an ABI 858 compatibility on 64 bit architecture. You have to recompile 859 userland programs that use getaddrinfo(3) on 64 bit 860 architecture. 861 86220050711: 863 RELENG_6 branched here. 864 86520050629: 866 The pccard_ifconfig rc.conf variable has been removed and a new 867 variable, ifconfig_DEFAULT has been introduced. Unlike 868 pccard_ifconfig, ifconfig_DEFAULT applies to ALL interfaces that 869 do not have ifconfig_ifn entries rather than just those in 870 removable_interfaces. 871 87220050616: 873 Some previous versions of PAM have permitted the use of 874 non-absolute paths in /etc/pam.conf or /etc/pam.d/* when referring 875 to third party PAM modules in /usr/local/lib. A change has been 876 made to require the use of absolute paths in order to avoid 877 ambiguity and dependence on library path configuration, which may 878 affect existing configurations. 879 88020050610: 881 Major changes to network interface API. All drivers must be 882 recompiled. Drivers not in the base system will need to be 883 updated to the new APIs. 884 88520050609: 886 Changes were made to kinfo_proc in sys/user.h. Please recompile 887 userland, or commands like `fstat', `pkill', `ps', `top' and `w' 888 will not behave correctly. 889 890 The API and ABI for hwpmc(4) have changed with the addition 891 of sampling support. Please recompile lib/libpmc(3) and 892 usr.sbin/{pmcstat,pmccontrol}. 893 89420050606: 895 The OpenBSD dhclient was imported in place of the ISC dhclient 896 and the network interface configuration scripts were updated 897 accordingly. If you use DHCP to configure your interfaces, you 898 must now run devd. Also, DNS updating was lost so you will need 899 to find a workaround if you use this feature. 900 901 The '_dhcp' user was added to support the OpenBSD dhclient. Be 902 sure to run mergemaster -p (like you are supposed to do every time 903 anyway). 904 90520050605: 906 if_bridge was added to the tree. This has changed struct ifnet. 907 Please recompile userland and all network related modules. 908 90920050603: 910 The n_net of a struct netent was changed to an uint32_t, and 911 1st argument of getnetbyaddr() was changed to an uint32_t, to 912 conform to POSIX-2001. These changes broke an ABI 913 compatibility on 64 bit architecture. With these changes, 914 shlib major of libpcap was bumped. You have to recompile 915 userland programs that use getnetbyaddr(3), getnetbyname(3), 916 getnetent(3) and/or libpcap on 64 bit architecture. 917 91820050528: 919 Kernel parsing of extra options on '#!' first lines of shell 920 scripts has changed. Lines with multiple options likely will 921 fail after this date. For full details, please see 922 http://people.freebsd.org/~gad/Updating-20050528.txt 923 92420050503: 925 The packet filter (pf) code has been updated to OpenBSD 3.7 926 Please note the changed anchor syntax and the fact that 927 authpf(8) now needs a mounted fdescfs(5) to function. 928 92920050415: 930 The NO_MIXED_MODE kernel option has been removed from the i386 931 amd64 platforms as its use has been superceded by the new local 932 APIC timer code. Any kernel config files containing this option 933 should be updated. 934 93520050227: 936 The on-disk format of LC_CTYPE files was changed to be machine 937 independent. Please make sure NOT to use NO_CLEAN buildworld 938 when crossing this point. Crossing this point also requires 939 recompile or reinstall of all locale depended packages. 940 94120050225: 942 The ifi_epoch member of struct if_data has been changed to 943 contain the uptime at which the interface was created or the 944 statistics zeroed rather then the wall clock time because 945 wallclock time may go backwards. This should have no impact 946 unless an snmp implementation is using this value (I know of 947 none at this point.) 948 94920050224: 950 The acpi_perf and acpi_throttle drivers are now part of the 951 acpi(4) main module. They are no longer built separately. 952 95320050223: 954 The layout of struct image_params has changed. You have to 955 recompile all compatibility modules (linux, svr4, etc) for use 956 with the new kernel. 957 95820050223: 959 The p4tcc driver has been merged into cpufreq(4). This makes 960 "options CPU_ENABLE_TCC" obsolete. Please load cpufreq.ko or 961 compile in "device cpufreq" to restore this functionality. 962 96320050220: 964 The responsibility of recomputing the file system summary of 965 a SoftUpdates-enabled dirty volume has been transferred to the 966 background fsck. A rebuild of fsck(8) utility is recommended 967 if you have updated the kernel. 968 969 To get the old behavior (recompute file system summary at mount 970 time), you can set vfs.ffs.compute_summary_at_mount=1 before 971 mounting the new volume. 972 97320050206: 974 The cpufreq import is complete. As part of this, the sysctls for 975 acpi(4) throttling have been removed. The power_profile script 976 has been updated, so you can use performance/economy_cpu_freq in 977 rc.conf(5) to set AC on/offline cpu frequencies. 978 97920050206: 980 NG_VERSION has been increased. Recompiling kernel (or ng_socket.ko) 981 requires recompiling libnetgraph and userland netgraph utilities. 982 98320050114: 984 Support for abbreviated forms of a number of ipfw options is 985 now deprecated. Warnings are printed to stderr indicating the 986 correct full form when a match occurs. Some abbreviations may 987 be supported at a later date based on user feedback. To be 988 considered for support, abbreviations must be in use prior to 989 this commit and unlikely to be confused with current key words. 990 99120041221: 992 By a popular demand, a lot of NOFOO options were renamed 993 to NO_FOO (see bsd.compat.mk for a full list). The old 994 spellings are still supported, but will cause annoying 995 warnings on stderr. Make sure you upgrade properly (see 996 the COMMON ITEMS: section later in this file). 997 99820041219: 999 Auto-loading of ancillary wlan modules such as wlan_wep has 1000 been temporarily disabled; you need to statically configure 1001 the modules you need into your kernel or explicitly load them 1002 prior to use. Specifically, if you intend to use WEP encryption 1003 with an 802.11 device load/configure wlan_wep; if you want to 1004 use WPA with the ath driver load/configure wlan_tkip, wlan_ccmp, 1005 and wlan_xauth as required. 1006 100720041213: 1008 The behaviour of ppp(8) has changed slightly. If lqr is enabled 1009 (``enable lqr''), older versions would revert to LCP ECHO mode on 1010 negotiation failure. Now, ``enable echo'' is required for this 1011 behaviour. The ppp version number has been bumped to 3.4.2 to 1012 reflect the change. 1013 101420041201: 1015 The wlan support has been updated to split the crypto support 1016 into separate modules. For static WEP you must configure the 1017 wlan_wep module in your system or build and install the module 1018 in place where it can be loaded (the kernel will auto-load 1019 the module when a wep key is configured). 1020 102120041201: 1022 The ath driver has been updated to split the tx rate control 1023 algorithm into a separate module. You need to include either 1024 ath_rate_onoe or ath_rate_amrr when configuring the kernel. 1025 102620041116: 1027 Support for systems with an 80386 CPU has been removed. Please 1028 use FreeBSD 5.x or earlier on systems with an 80386. 1029 103020041110: 1031 We have had a hack which would mount the root filesystem 1032 R/W if the device were named 'md*'. As part of the vnode 1033 work I'm doing I have had to remove this hack. People 1034 building systems which use preloaded MD root filesystems 1035 may need to insert a "/sbin/mount -u -o rw /dev/md0 /" in 1036 their /etc/rc scripts. 1037 103820041104: 1039 FreeBSD 5.3 shipped here. 1040 104120041102: 1042 The size of struct tcpcb has changed again due to the removal 1043 of RFC1644 T/TCP. You have to recompile userland programs that 1044 read kmem for tcp sockets directly (netstat, sockstat, etc.) 1045 104620041022: 1047 The size of struct tcpcb has changed. You have to recompile 1048 userland programs that read kmem for tcp sockets directly 1049 (netstat, sockstat, etc.) 1050 105120041016: 1052 RELENG_5 branched here. For older entries, please see updating 1053 in the RELENG_5 branch. 1054 1055COMMON ITEMS: 1056 1057 General Notes 1058 ------------- 1059 Avoid using make -j when upgrading. From time to time in the 1060 past there have been problems using -j with buildworld and/or 1061 installworld. This is especially true when upgrading between 1062 "distant" versions (eg one that cross a major release boundary 1063 or several minor releases, or when several months have passed 1064 on the -current branch). 1065 1066 Sometimes, obscure build problems are the result of environment 1067 poisoning. This can happen because the make utility reads its 1068 environment when searching for values for global variables. 1069 To run your build attempts in an "environmental clean room", 1070 prefix all make commands with 'env -i '. See the env(1) manual 1071 page for more details. 1072 1073 When upgrading from one major version to another it is generally 1074 best to upgrade to the latest code in the currently installed branch 1075 first, then do an upgrade to the new branch. This is the best-tested 1076 upgrade path, and has the highest probability of being successful. 1077 Please try this approach before reporting problems with a major 1078 version upgrade. 1079 1080 To build a kernel 1081 ----------------- 1082 If you are updating from a prior version of FreeBSD (even one just 1083 a few days old), you should follow this procedure. It is the most 1084 failsafe as it uses a /usr/obj tree with a fresh mini-buildworld, 1085 1086 make kernel-toolchain 1087 make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE 1088 make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE 1089 1090 To test a kernel once 1091 --------------------- 1092 If you just want to boot a kernel once (because you are not sure 1093 if it works, or if you want to boot a known bad kernel to provide 1094 debugging information) run 1095 make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel 1096 nextboot -k testkernel 1097 1098 To just build a kernel when you know that it won't mess you up 1099 -------------------------------------------------------------- 1100 This assumes you are already running a 5.X system. Replace 1101 ${arch} with the architecture of your machine (e.g. "i386", 1102 "alpha", "amd64", "ia64", "pc98", "sparc64", etc). 1103 1104 cd src/sys/${arch}/conf 1105 config KERNEL_NAME_HERE 1106 cd ../compile/KERNEL_NAME_HERE 1107 make depend 1108 make 1109 make install 1110 1111 If this fails, go to the "To build a kernel" section. 1112 1113 To rebuild everything and install it on the current system. 1114 ----------------------------------------------------------- 1115 # Note: sometimes if you are running current you gotta do more than 1116 # is listed here if you are upgrading from a really old current. 1117 1118 <make sure you have good level 0 dumps> 1119 make buildworld 1120 make kernel KERNCONF=YOUR_KERNEL_HERE 1121 [1] 1122 <reboot in single user> [3] 1123 mergemaster -p [5] 1124 make installworld 1125 make delete-old 1126 mergemaster [4] 1127 <reboot> 1128 1129 1130 To cross-install current onto a separate partition 1131 -------------------------------------------------- 1132 # In this approach we use a separate partition to hold 1133 # current's root, 'usr', and 'var' directories. A partition 1134 # holding "/", "/usr" and "/var" should be about 2GB in 1135 # size. 1136 1137 <make sure you have good level 0 dumps> 1138 <boot into -stable> 1139 make buildworld 1140 make buildkernel KERNCONF=YOUR_KERNEL_HERE 1141 <maybe newfs current's root partition> 1142 <mount current's root partition on directory ${CURRENT_ROOT}> 1143 make installworld DESTDIR=${CURRENT_ROOT} 1144 make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd 1145 make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT} 1146 cp /etc/fstab ${CURRENT_ROOT}/etc/fstab # if newfs'd 1147 <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition> 1148 <reboot into current> 1149 <do a "native" rebuild/install as described in the previous section> 1150 <maybe install compatibility libraries from ports/misc/compat*> 1151 <reboot> 1152 1153 1154 To upgrade in-place from 5.x-stable to current 1155 ---------------------------------------------- 1156 <make sure you have good level 0 dumps> 1157 make buildworld [9] 1158 make kernel KERNCONF=YOUR_KERNEL_HERE [8] 1159 [1] 1160 <reboot in single user> [3] 1161 mergemaster -p [5] 1162 make installworld 1163 make delete-old 1164 mergemaster -i [4] 1165 <reboot> 1166 1167 Make sure that you've read the UPDATING file to understand the 1168 tweaks to various things you need. At this point in the life 1169 cycle of current, things change often and you are on your own 1170 to cope. The defaults can also change, so please read ALL of 1171 the UPDATING entries. 1172 1173 Also, if you are tracking -current, you must be subscribed to 1174 freebsd-current@freebsd.org. Make sure that before you update 1175 your sources that you have read and understood all the recent 1176 messages there. If in doubt, please track -stable which has 1177 much fewer pitfalls. 1178 1179 [1] If you have third party modules, such as vmware, you 1180 should disable them at this point so they don't crash your 1181 system on reboot. 1182 1183 [3] From the bootblocks, boot -s, and then do 1184 fsck -p 1185 mount -u / 1186 mount -a 1187 cd src 1188 adjkerntz -i # if CMOS is wall time 1189 Also, when doing a major release upgrade, it is required that 1190 you boot into single user mode to do the installworld. 1191 1192 [4] Note: This step is non-optional. Failure to do this step 1193 can result in a significant reduction in the functionality of the 1194 system. Attempting to do it by hand is not recommended and those 1195 that pursue this avenue should read this file carefully, as well 1196 as the archives of freebsd-current and freebsd-hackers mailing lists 1197 for potential gotchas. 1198 1199 [5] Usually this step is a noop. However, from time to time 1200 you may need to do this if you get unknown user in the following 1201 step. It never hurts to do it all the time. You may need to 1202 install a new mergemaster (cd src/usr.sbin/mergemaster && make 1203 install) after the buildworld before this step if you last updated 1204 from current before 20020224 or from -stable before 20020408. 1205 1206 [8] In order to have a kernel that can run the 4.x binaries 1207 needed to do an installworld, you must include the COMPAT_FREEBSD4 1208 option in your kernel. Failure to do so may leave you with a system 1209 that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 1210 is required to run the 5.x binaries on more recent kernels. 1211 1212 Make sure that you merge any new devices from GENERIC since the 1213 last time you updated your kernel config file. 1214 1215 [9] When checking out sources, you must include the -P flag to have 1216 cvs prune empty directories. 1217 1218 If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1219 "?=" instead of the "=" assignment operator, so that buildworld can 1220 override the CPUTYPE if it needs to. 1221 1222 MAKEOBJDIRPREFIX must be defined in an environment variable, and 1223 not on the command line, or in /etc/make.conf. buildworld will 1224 warn if it is improperly defined. 1225FORMAT: 1226 1227This file contains a list, in reverse chronological order, of major 1228breakages in tracking -current. Not all things will be listed here, 1229and it only starts on October 16, 2004. Updating files can found in 1230previous releases if your system is older than this. 1231 1232Copyright information: 1233 1234Copyright 1998-2005 M. Warner Losh.
