1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M. Warner Losh 4<imp@village.org>. Please send new entries directly to him. See end 5of file for further details. For commonly done items, please see the 6COMMON ITEMS: section later in the file. 7 820010628: 9 The kernel compile module has moved from src/sys/compile/FOO 10 to src/sys/${MACHINE}/compile/FOO. 11 1220010625: 13 The pccard modem issue has been corrected. OLDCARD support is 14 still a little weak in -current. slot 1 is known not to work 15 on some TI based cardbus bridges. Some cardbus bridges do not 16 properly detect insert/removal events. IRQ configuration needs 17 more safety belts. 18 1920010617: 20 Softupdates problems have been corrected. 21 2220010614: 23 Peter ripped out the linkerset support. You must, as always, 24 rerun config after you cvsup if you are using the traditional 25 kernel building methods. 26 2720010613: 28 pccard modems may not work with current after 20010604 date. Some 29 do, others result in panics. *MAKE*SURE* that you update your 30 config and /etc/rc.conf ala the 20010604 entry, or you will have 31 problems (this issue will be fixed, it just hasn't been yet). 32 3320010613: 34 SOFTUPDATES seem to be broken since the middle of May or so. Do not 35 use them in current. You can disable softupdates on all mounted 36 partitions, or remove SOFTUPDATES the kernel config file. 37 3820010612: 39 After Peter's commits to the hints code, people have been noticing 40 that certain devices are attached (or try to) twice. This is due 41 to having both static hints as well as a /boot/device.hints. To 42 work around this issue, please use only one or the other mechanism 43 until this bug is fixed. 44 45 Please note that a feature of config is that if you have config 46 file FOO and FOO.hints, it automatically adds FOO.hints to the 47 hints.c file, wheather you want it to or not. 48 4920010610: 50 Locale names have changed to match other systems better. 51 5220010604: 53 pccard support for pci cards has been committed. You must change 54 your /etc/pccard.conf irq lines. It must match the irq used by 55 pcic device. Interrupt storms may result if you fail to do this. 56 Interrupt storms look a lot like a hang. 57 58 You must also install a new pccardd, otherwise you will get an 59 interrupt storm at card reset time (just after it tells you what 60 it is). 61 62 pccardd_flags="-I" is necessary for the time being. It tells pccardd 63 not to ask the kernel if the interrupt is really free or not before 64 using it. You can either change the /etc/pccard.conf irq lines to 65 match pcic, or add "-i X" to the pccardd_flags. 66 6720010530: 68 INSTALL=install -C is being deprecated. If you want to do this, 69 use COPY=-C instead. The former method will be supported for only 70 a limited time. If you see 71 72install: warning: the -d and -C options may not be specified together 73 74 in your makeworld, then you need to migrate towards using 75 COPY=-C. 76 7720010525: 78 It appears that vm is now stable enough to use again. However, 79 there may be other problems, so caution is still urged. alpha 80 definitely is in bad shape. 81 8220010521: 83 Minor repo damanged has happened. This may cause problems 84 with cvsup of ports. If you get errors, please see 85 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=27495 86 at the bottom for details on a workaround. The error message 87 is 88Updater failed: Cannot delete "/usr/ports/www/jakarta-tomcat/files": Directory not empty 89 9020010520: 91 Vm and/or swapping are busted on -current. Please be patient. 92 9320010519: 94 pccard has had much reorganizational work done to it over 95 the past few days. Everything should still work, but if 96 not, please contact imp@freebsd.org. 97 9820010517: 99 ata ioctl changed. Make sure to recompile both kernel and 100 userland at the same time. 101 10220010517: 103 New ncurses imported. 104 10520010512: 106 DEVFS is now opt out, not opt in. Barring major problems, this 107 will be the only way to go starting July 1. 108 10920010502: 110 Perl breakage in 20010501 was corrected at 14:18:33 PDT. 111 11220010501: 113 Building perl was broken at 02:25:25 PDT. 114 11520010430: 116 The bug in 20010429 was corrected at 07:35:37 PDT. It is safe to 117 go back in the water. 118 11920010429: 120 A bad bug was committed at 04:48:42 PDT. Don't use kernels after 121 this date, but before the correction date. 122 12320010423: 124 old fsck and new kernel interactions appear to have been fixed. 125 12620010411: 127 fsck and the kernel were changed to handle some optimizations 128 to directory layout. This breaks backward compatibility. 129 Update only if you understand that you must not use the old 130 fsck with the new kernel ever. 131 13220010330: 133 fsck has changed the meaning of the pass column in /etc/fstab. 134 Please see the cvs commit to fsck.8 or the fsck.8 man page for 135 details. It is unclear if changes to /etc/fstab are necessary. 136 13720010319: 138 portmap had changed name to rpcbind for maximum POLA in your 139 current world. /etc/hosts.{allow,deny} needs changes. nfs and 140 other rpc based programs that rely on portmapper will not work 141 without updates to /etc/hosts.{allow,deny} and /etc/netcofnig. 142 14320010315: 144 ata subsystem changes. ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC 145 and ATA_ENABEL_TAGS are no longer kernel options. They have 146 been replaced by tunables. See ata.4 for details. 147 14820010312: 149 The fxp driver was converted to use miibus. If you compile 150 fxp into your kernel statically, you will need to add miibus. 151 15220010312: 153 The wi device now defaults to BSS (infrastructure) mode 154 instead of ad-hoc. 155 15620010310: 157 /dev/urandom should be a symbolic link to /dev/random now. 158 Users of current not using DEVFS need to run MAKEDEV std. 159 ssh might not work if you don't. 160 16120010220: 162 The problems with libc have been corrected. It is now mostly 163 safe to go back into the water. 164 16520010211: 166 The size of FILE was changed. This breaks upgrading. If 167 you must upgrade, be prepared for pain. It also breaks almost 168 all binaries that you've compiled on -current. You are warned 169 that before upgrading would be a good time to do a level 0 170 dump of your system. No, really, I mean it this time. 171 172 To get to the new system, you'll need to use the following 173 workaround. Hopefully this can be sorted out so that we 174 don't have to move this to the updating section. 175 176 To get around the installworld problem, do: 177 # cd /usr/src/usr.bin/sed 178 # make install 179 # cd /usr/src 180 # make installworld 181 If that doesn't work, then try: 182 # make -k installworld 183 # make installworld 184 18520010207: 186 DEVFS is now the default. If you use vinum, make sure that you 187 do not include devfs in your kernel as problems result. 188 18920010205: 190 FFS_ROOT and CD9660_ROOT have been removed or deprecated. 191 Remove them from your config. 192 19320010122: 194 ****************************** WARNING ****************************** 195 buildkernel has been changed slightly 196 ****************************** WARNING ****************************** 197 KERNCONF replaces the variable KERNEL for buildkernel. You 198 should update your scripts and make.conf accordingly. 199 20020010119: 201 config has changed to allow DEV_FOO as a replacement for NFOO. 202 This requires a new config to build correctly. 203 20420010116: 205 The kerrnel option I386_CPU is now mutually exclusive with the 206 other cpu types. If you have an i386 system, be sure that it 207 only had this line. Remove it for all other configurations. 208 20920010110: 210 Changes to the kernel require it and burncd be in sync. 211 21220010102: 213 Everyone who has hw.sndunit set to something in 214 /etc/sysctl.conf, it is now hw.snd.unit. 215 21620010101: 217 ex and vi were broken by some changes to sys/queue.h. If you 218 have a bad vi, you will see make buildworld fail with a core 219 dump while building termcap. You can work around this problem 220 by adding -k to your make buildworld. This will cause the 221 build to complete and install a new vi. Once that's done, you 222 can rebuild again without the -k to pick up anything that 223 might have been ignored by the -k option. 224 225 Others have suggested that you can just rebuild libc if your 226 vi/ex is dynamically linked, but I've not received any reports 227 of this working. 228 22920001228: 230 There have been some changes to libcrypt in -current. The 231 libscrypt/libdescrypt symlink sillyness is gone and the installed 232 libcrypt is fully functional. Be aware of this. 233 23420001218: 235 Linksys Fast Ethernet PCCARD cards supported by the ed driver 236 now require the addition of flag 0x80000 to their config line 237 in pccard.conf(5). This flag is not optional. These Linksys 238 cards will not be recognized without it. 239 24020001205: 241 Important new FreeBSD-version stuff: PAM support has been worked 242 in, partially from the "Unix" OpenSSH version. This requires 243 adding the following in pam.conf: 244 245 sshd auth sufficient pam_skey.so 246 sshd auth required pam_unix.so try_first_pass 247 sshd session required pam_permit.so 248 24920001031: 250 cvs updated to 1.11. 251 25220001020: 253 The random device needs more entropy, so you need to make sure 254 that you've run mergemaster to get a /etc/rc which will seed 255 /dev/random. If you don't and the system hangs after ldconfig, 256 then banging on the keyboard randomly until it unhangs is one 257 workaround. 258 25920001010: 260 ****************************** WARNING ****************************** 261 Sendmail has been updated. 262 ****************************** WARNING ****************************** 263 o mail.local(8) is no longer installed as a set-user-id binary. 264 o sendmail(8) is now built with STARTTLS support unless NO_OPENSSL 265 is set. 266 o The default /etc/mail/sendmail.cf disables the SMTP EXPN and VRFY 267 commands. 268 o Now using sendmail's version of vacation(1). 269 o The sendmail cf building tools (contrib/sendmail/cf) are installed 270 in /usr/share/sendmail/cf. 271 o sendmail.cw changed to local-host-names 272 273 More details can be found at 274 http://people.freebsd.org/~imp/UPDATING/sendmail-20001010 275 27620001009: 277 The ports tree's new layout is in place. Be sure to update 278 your entire ports tree, or you will have problems. 279 28020001006: 281 The perl build procedure no longer installs miniperl, nor uses 282 the installed miniperl. It is recommended that you delete 283 /usr/bin/miniperl. 284 28520001005: 286 This weekend the ports tree will be updated to a new layout. 287 It will be in an inconsistent state until noted in the UPDATING 288 file, or with asami-san's message to the relevant mailing 289 lists. With this new layout, you'll need to update the whole 290 tree for anything to work. 291 29220000928: 293 There was a change in the passwd format. Need more information. 294 29520000916: 296 /boot/kernel/kernel.ko -> /boot/kernel/kernel change has taken 297 place. Please update boot loader (not the boot blocks) at the 298 same time as your kernel. 299 30020000914: 301 The new pmtimer device is necessary for laptops. Failure to 302 include the device will cause suspended laptops losing time 303 when they resume. Include 304 device pmtimer 305 in your config file and 306 hint.pmtimer.0.at="isa" 307 to your /boot/device.hints file. 308 30920000911: 310 The random device has been turned into a (pseudo-)device, 311 rather than an option. The supplied kernel config files have 312 been updated. You will need to do something similar in your 313 own kernel config file. 314 Remove: 315 options RANDOMDEV 316 Add: 317 device random 318 If you prefer to load the loadable module, you need to do 319 nothing. 320 32120000909: 322 The random device module has been renamed from randomdev.ko to 323 random.ko. You will need to edit your /boot/loader.conf to 324 reflect this if you load this module at boot time. 325 The line should read: 326 random_load="YES" 327 32820000907: 329 The SMPNG commit has happened. It should work, but if it 330 doesn't, fallback to the PRE_SMPNG CVS tag. There are likely 331 to be a variety of minor issues. Please see 20000905 to make 332 sure you don't have model loading problems which might at 333 first blush appear related to SMP. 334 33520000906: 336 nsswitch has been imported from NetBSD. Among other things, 337 this means that /etc/host.conf is no longer used. See 338 nsswitch.conf(5) instead. Note that at boot time rc.network 339 will attempt to produce a new nsswitch.conf file for you if you 340 don't have one, and you have host.conf. 341 34220000905: 343 The ucred structure changed size. This breaks the interface 344 that mountd uses. Trying to use an older mountd with a newer 345 kernel guarantees a panic. This means that you need to use 346 kernels newer than today only with matching mountd, but you 347 needed to do that anyway with the boot loader changes. 348 34920000905: 350 The boot loader has been updated. The new default kernel is 351 now /boot/kernel/kernel.ko. The new default module location 352 is /boot/kernel. 353 354 You *MUST* upgrade your boot loader and kernel at the same time. 355 The easiest way to do this is to do the buildworld/buildkernel/ 356 installkernel/installworld dance. 357 358 Furthermore, you are urged to delete your old /modules directory 359 before booting the new kernel, since kldload will find stale 360 modules in that directory instead of finding them in the correct 361 path, /boot/kernel. The most common complaint that this cures 362 is that the linux module crashes your machine after the update. 363 364 if [ ! -d /boot/kernel.old ]; then 365 mv /modules.old /boot/kernel.old 366 chflags noschg /kernel.old 367 mv /kernel.old /boot/kernel.old/kernel.ko 368 chflags schg /boot/kernel.old/kernel.ko 369 fi 370 37120000904: 372 A new issue with the sendmail upgrade has come to light. 373 /etc/aliases has moved to /etc/mail/aliases. Mergemaster will 374 incorrectly install the default aliases in /etc/mail rather than 375 move the old one from /etc. So you'll need to manually move the 376 file, create a symbolic link, remove the old /etc/aliases.db and 377 run newaliases. For safety sake, you should stop sendmail 378 while doing this and run the upgrade when locally sourced email 379 is not likely to be generated. 380 38120000825: 382 /boot/device.hints is now required for installkernel to 383 succeed. You should copy GENERIC.hints for your architecture 384 into /boot/device.hints. If and only if you compile hints 385 into your kernel, then this file may be empty. Please note, 386 if you have an empty or missing /boot/device.hints file and 387 you neglected to compile hints into your kernel, no boot 388 messages will appear after the boot loader tries to start the 389 kernel. 390 39120000821: 392 If you do NOT have ``options RANDOMDEV'' in your kernel and 393 you DO want the random device then add randomdev_load="YES" to 394 /boot/loader.conf. 395 39620000812: 397 suidperl is now always built and installed on the system, but 398 with permissions of 511. If you have applications that use 399 this program, you are now required to add ENABLE_SUIDPERL=true 400 to /etc/make.conf. If you forget to do this, 401 chmod 4511 /usr/bin/suidperl 402 will fix this until the next build. 403 40420000812: 405 sendmail has been updated from 8.9.3 to 8.11.0. Some of the more 406 visible changes that may immediately affect your configuration 407 include: 408 - New default file locations from src/contrib/sendmail/cf/README 409 - newaliases limited to root and trusted users 410 - MSA port (587) turned on by default 411 - New queue file naming system so can't go from 8.11 -> 8.9 412 - FEATURE(`rbl') renamed to FEATURE(`dnsbl') 413 - FEATURE(`nullclient') is more full featured 414 - FEATURE(`nouucp') requires an argument: `reject' or `nospecial' 415 - mail.local FreeBSD-only -b option changed to -B 416 - See src/contrib/sendmail/RELEASE_NOTES for more info 417 41820000810: 419 suidperl (aka sperl) is no longer build by default. You must 420 specifically define BUILD_SUIDPERL to "true" for it to be build. 421 Furthermore, we recommend that you remove /usr/bin/sperl* and 422 /usr/bin/suidperl files from your system unless you have a 423 specific use for it. 424 42520000729: 426 Networking defaults have been tightened. Anybody upgrading 427 /etc/defaults/rc.conf needs to add the following lines to 428 /etc/rc.conf if they want to have the same setup 429 afterwards (unless the variables already are set, of course): 430 # Enable network daemons for user convenience. 431 inetd_enable="YES" 432 portmap_enable="YES" 433 sendmail_enable="YES" 434 43520000728: 436 If you have null_load="YES" in your /boot/loader.conf, you 437 will need to change that to nullfs_load="YES". 438 43920000728: 440 The "installkernel" target has changed slightly. Now even if 441 you override KERNEL e.g. 'make installkernel KERNEL=MYKERNEL' 442 it will install the MYKERNEL file (built with the buildkernel 443 target) as /kernel rather than /MYKERNEL. Those who have 444 updated their /boot/loader.conf files to point to /MYKERNEL 445 should remove that entry or perform manual rename of /kernel 446 to /MYKERNEL. 447 44820000711: 449 If you use CVSUP or CTM to get CVS trees, AND you used to get 450 the old crypto files from internat.freebsd.org AND you check 451 out files from the CVS tree with the cvs command, please read 452 http://people.freebsd.org/~imp/internat.txt 453 for details on potential problems that you might have and how 454 to get around them. 455 456 If you are merely a mirror, or don't answer yes to each of the 457 clauses above, you needn't worry. 458 45920000711: 460 /etc/security has been updated to print the inode number of 461 setuid programs that have changed. You will see a large spike 462 in the number of changed programs the first time when you run 463 mergemaster to get a new /etc/security. 464 46520000710: 466 /dev/random now has good entropy collection (from the keyboard 467 and sysmouse drivers). Please ensure that either `options 468 RANDOMDEV' is present in your kernel config file or that 469 `randomdev_load="YES"' is in your /boot/loader.conf. If you do 470 not have the /dev/random driver, OpenSSL (and consequently 471 lots of crypto tools (like SSH)) will fail with strange 472 errors. (see below, 20000624). 473 474 FreeBSD-current is safe again to run Crypto. 475 47620000709: 477 phk made the malloc default options AJ. This may slow things 478 down and uncover other latent bugs in the code. If you need to 479 run at full speed, you can disable this by doing the following: 480 ln -s aj /etc/malloc.conf 481 48220000706: 483 libftpio's version was accidentally bumped a few days ago. This 484 has been corrected. You may need to remove /usr/lib/libftpio.so.6 485 before doing your next buildworld/installworld pair. It certainly 486 won't hurt to remove it before the update procedure. It will 487 break fetch until a new one is built, but ftp can be used in the 488 interim if needed. 489 49020000705: 491 The crypto packages have changed for the cvsup. This has been done 492 in a backward compatible way, but the old packages will go away at 493 some point in the future. Look at /usr/share/examples/cvsup for 494 details. 495 49620000704: 497 With the new sys/modules/sound/drivers/*, you will need to 498 set SYSDIR until you do an installworld after July 7th. 499 50020000704: 501 rc.shutdown and rc will now call the rc.d scripts with start 502 or stop. This may cause some harmless warnings from older 503 rc.d scripts that haven't been updated. 504 50520000630: 506 The libfetch based version of fetch has gone into the tree. 507 Minor problems may result on some of the less popular sites, 508 which should be reported to des@freebsd.org. 509 51020000625: 511 From approximately this date forward, one must have the crypto 512 system installed in order to build the system and kernel. 513 While not technically strictly true, one should treat it as 514 required and grab the crypto bits. If you are grabbing CVS 515 trees, src-all and cvs-crypto should be treated as if they 516 were required. You should check with the latest collections 517 to make sure that these haven't changed. 518 51920000624: 520 Mark Murray just committed the first parts of a cleanup of 521 /dev/zero, et al. This is also cleaning up /dev/random. 522 The entropy is disconnected, so DO NOT USE VERSIONS OF FREEBSD 523 -CURRENT FROM THIS POINT FORWARD for cryptographic services 524 until Mark can merge in the fixes to this work in progress. 525 openssh and openssl should not be used to generate keys from this 526 date to the completion of the work. 527 528 If you must operate at this reduced level of security, add ' 529 options RANDOMDEV' to your kernel or modload the randomdev 530 module. You may also need to copy a new MAKEDEV to /dev and 531 recreate the random and urandom devices. 532 53320000622: 534 The license on the softupdates is now a standard 2 clause 535 BSD license. You may need to remove your symbolic links 536 that used to be required when updating. 537 53820000621: 539 Scott Flatman <sf@aracnet.com> sent in a decent write-up on 540 the config file update procedure. 541 http://people.freebsd.org/~imp/config-upd.html 542 NOTE: LINT is gone. It has been replaced with NOTES. NOTES 543 isn't buildable. However, you can generate a LINT file. 544 54520000620: 546 Binutils 2.10 have hit the tree, or will shortly. As soon 547 as they do, the problem noted in 20000522 will be resolved and 548 that workaround will no longer be required. 549 55020000615: 551 phk removed the compatibility creation of wd devices in the 552 ad driver. If you haven't done so already, you must update 553 your fstab, etc to use the ad devices instead of the wd 554 devices. 555 556 In addition, you'll need to update your boot blocks to a 557 more modern version, if you haven't already done so. Modern 558 here means 4.0 release or newer (although older releases 559 may work). 560 56120000612: 562 Peter took an axe to config(8). Be sure that you read his mail 563 on the topic before even thinking about updating. You will 564 need to create a /boot/device.hints or add a hints directive 565 to your config file to compile them in statically. The format 566 of the config file has changed as well. Please see GENERIC or 567 NEWCARD for examples of the new format. 568 56920000522: 570 A new set of binutils went into the tree today. Anybody 571 building a kernel after this point is advised that they need 572 to rebuild their binutils (or better yet do a 573 buildworld/installworld) before building a new kernel. 574 575 Due to bugs in binutils, using malloc options (eg /etc/malloc.conf 576 or MALLOC_OPTIONS env var) J will cause ld to dump core. It 577 is recommended that you don't set this option until the problem 578 is resolved. 579 58020000513: 581 The ethernet drivers were all updated to clean up the BPF handling. 582 58320000510: 584 The problems with boot blocks on the alphas have been corrected. 585 This will require some care in updating alphas. A new libstand 586 is requires for the boot blocks to build properly. 587 58820000503: 589 Recompile all kld modules. Proper version dependency info 590 is now available. 591 59220000502: 593 Modules have been disconnected from the buildworld tree and 594 connected to the kernel building instead. 595 59620000427: 597 You may need to build gperf 598 cd /usr/src/gnu/usr.bin/gperf && make depend all install 599 when upgrading from 4.0 -> current. The build system now uses 600 an option only in -current. 601 60220000417: 603 The method that we brand ELF binaries has changed to be more 604 acceptable to the binutils maintainers. You will need to 605 rebrand your ELF binaries that aren't native. One problem 606 binary is the Linux ldconfig. After your make world, but 607 before you reboot, you'll need to issue: 608 brandelf -t Linux /compat/linux/sbin/ldconfig 609 if you have Linux compatibility enabled on your machine. 610 61120000320: 612 If you have really bad/marginal IDE drives, you may find they 613 don't work well. Use pio mode instead. The easiest way to 614 cope if you have a problem combination is to add: 615 /sbin/sysctl -w hw.atamodes=pio,pio,pio,pio 616 to the start of /etc/rc.conf. 617 61820000319: 619 The ISA and PCI compatibility shims have been connected to the 620 options COMPAT_OLDISA and COMPAT_OLDPCI. If you are using old 621 style PCI or ISA drivers (i.e. tx, voxware, etc.) you must 622 include the appropriate option in your kernel config. Drivers 623 using the shims should be updated or they won't ship with 624 5.0-RELEASE, targeted for 2001. 625 62620000318: 627 We've entered the traditional post release dumping party. 628 Large kernel changes are being committed and are in the 629 works. It is important to keep the systems' klds and kernel 630 in sync as kernel interfaces and structures are changing. 631 Before reporting kernel panics, make sure that all modules 632 that you are loading are up to date. 633 63420000315: 635 If you are upgrading from an older version of FreeBSD, you 636 need to update your boot blocks as well. 'disklabel -B ad0' 637 will do the trick. This isn't critical until you remove your 638 wd device entries in /dev, at which point your system will not 639 boot. 640 64120000315: 642 4.0 RELEASE shipped. Please see the 4.0 UPDATING file for how 643 to upgrade to 4.0 from 3.x. 644 645COMMON ITEMS: 646 647 General Notes 648 ------------- 649 Avoid using make -j when upgrading. From time to time in the 650 past there have been problems using -j with buildworld and/or 651 installworld. This is especially true when upgrading between 652 "distant" versions (eg one that cross a major release boundary 653 or several minor releases, or when several months have passed 654 on the -current branch). 655 656 To build a kernel 657 ----------------- 658 If you are updating from a prior version of FreeBSD (even one just 659 a few days old), you should follow this procedure. With a 660 /usr/obj tree with a fresh buildworld, 661 make buildkernel KERNCONF=YOUR_KERNEL_HERE 662 make installkernel KERNCONF=YOUR_KERNEL_HERE 663 664 To just build a kernel when you know that it won't mess you up 665 -------------------------------------------------------------- 666 cd src/sys/{i386,alpha}/conf 667 config KERNEL_NAME_HERE [1] 668 cd ../../compile/KERNEL_NAME_HERE 669 make depend 670 make 671 make install 672 673 [1] If in doubt, -r might help here. 674 675 If this fails, go to the "To build a kernel" section. 676 677 To rebuild everything and install it on the current system. 678 ----------------------------------------------------------- 679 make world 680 Build a new kernel, see above. 681 682 To upgrade from 4.x-stable to current 683 ------------------------------------- 684 make buildworld 685 make buildkernel KERNCONF=YOUR_KERNEL_HERE 686 cp src/sys/${MACHINE_ARCH}/conf/GENERIC.hints /boot/device.hints [2] 687 make installkernel KERNCONF=YOUR_KERNEL_HERE 688 reboot in single user [3] 689 make installworld 690 mergemaster 691 [1] 692 <reboot> 693 694 Make sure that you've read the UPDATING file to understand the 695 tweaks to various things you need. At this point in the life 696 cycle of current, things change often and you are on your own 697 to cope. The defaults can also change, so please read ALL of 698 the UPDATING entries. 699 700 Also, if you are tracking -current, you must be subscribed to 701 freebsd-current@freebsd.org. Make sure that before you update 702 your sources that you have read and understood all the recent 703 messages there. If in doubt, please track -stable which has 704 much fewer pitfalls. 705 706 [1] If you have third party modules, such as vmware, you 707 should disable them at this point so they don't crash your 708 system on reboot. 709 710 [2] If you have legacy ISA devices, you may need to create 711 your own device.hints to reflect your unique hardware 712 configuration. 713 714 [3] From the bootblocks, boot -s, and then do 715 fsck -p 716 mount -u / 717 mount -a 718 cd /usr/src 719 adjkerntz -i # if COMS is wall time 720 721FORMAT: 722 723This file contains a list, in reverse chronological order, of major 724breakages in tracking -current. Not all things will be listed here, 725and it only starts on March 15, 2000. Updating files can found in 726previous releases if your system is older than this. 727 728Please filter your entries through Warner Losh (imp@village.org) so 729that the style, formatting, etc of this file can be maintained. 730 731Copyright information: 732 733Copyright 1998, 2001 M.
