If you have trouble bootstrapping 15a46954e2SWarner Loshfrom older versions of FreeBSD, try WITHOUT_CLANG and WITH_GCC to bootstrap to 16a8f2a2b9SEd Mastethe tip of head, and then rebuild without this option. The bootstrap process 17a8f2a2b9SEd Mastefrom older version of current across the gcc/clang cutover is a bit fragile. 184f1def68SWarner Losh 19ae940db1SGlen BarberNOTE TO PEOPLE WHO THINK THAT FreeBSD 12.x IS SLOW: 20981b538fSGlen Barber FreeBSD 12.x has many debugging features turned on, in both the kernel 21456b5dd8SWarner Losh and userland. These features attempt to detect incorrect use of 22456b5dd8SWarner Losh system primitives, and encourage loud failure through extra sanity 23456b5dd8SWarner Losh checking and fail stop semantics. They also substantially impact 24456b5dd8SWarner Losh system performance. If you want to do performance measurement, 25456b5dd8SWarner Losh benchmarking, and optimization, you'll want to turn them off. This 26456b5dd8SWarner Losh includes various WITNESS- related kernel options, INVARIANTS, malloc 27456b5dd8SWarner Losh debugging flags in userland, and various verbose features in the 28456b5dd8SWarner Losh kernel. Many developers choose to disable these features on build 2999e449f2SJason Evans machines to maximize performance. (To completely disable malloc 3099e449f2SJason Evans debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely 3199e449f2SJason Evans disable the most expensive debugging functionality run 32fca3dcdfSWarner Losh "ln -s 'abort:false,junk:false' /etc/malloc.conf".) 335ad05815SWarner Losh 345ad05815SWarner Losh 355ad05815SWarner Losh****************************** SPECIAL WARNING: ****************************** 365ad05815SWarner Losh 375ad05815SWarner Losh Due to a bug in some versions of clang that's very hard to workaround in 385ad05815SWarner Losh the upgrade process, to upgrade to -current you must first upgrade 39fca3dcdfSWarner Losh either stable/9 after r286035 or stable/10 after r286033 (including 40fca3dcdfSWarner Losh 10.3-RELEASE) or current after r286007 (including stable/11 and 41fca3dcdfSWarner Losh 11.0-RELEASE). These revisions post-date the 10.2 and 9.3 releases, so 42fca3dcdfSWarner Losh you'll need to take the unusual step of upgrading to the tip of the 43fca3dcdfSWarner Losh stable branch before moving to 11 or -current via a source upgrade. 4490136961SWarner Losh stable/11 and 11.0-RELEASE have working newer compiler. This differs 4590136961SWarner Losh from the historical situation where one could upgrade from anywhere on 4690136961SWarner Losh the last couple of stable branches, so be careful. 4790136961SWarner Losh 4890136961SWarner Losh If you're running a hybrid system on 9.x or 10.x with an updated clang 4990136961SWarner Losh compiler or are using an supported external toolchain, the build system 5090136961SWarner Losh will allow the upgrade. Otherwise it will print a reminder. 515ad05815SWarner Losh 525ad05815SWarner Losh****************************** SPECIAL WARNING: ****************************** 53efc06131SSam Leffler 549949595eSAdrian Chadd20170524: 559949595eSAdrian Chadd The ath(4) and ath_hal(4) modules now build piecemeal to allow for 569949595eSAdrian Chadd smaller runtime footprint builds.

Upgrading in place requires care and 90dcfffd04SEd Maste adherence to the documented upgrade procedure. 91dcfffd04SEd Maste 92dcfffd04SEd Maste If using a custom kernel configuration ensure that the 93dcfffd04SEd Maste COMPAT_FREEBSD11 option is included (as during the upgrade the 94dcfffd04SEd Maste system will be running the ino64 kernel with the existing world). 95dcfffd04SEd Maste 96dcfffd04SEd Maste For the safest in-place upgrade begin by removing previous build 97dcfffd04SEd Maste artifacts via "rm -rf /usr/obj/*". Then, carefully follow the 98dcfffd04SEd Maste full procedure documented below under the heading "To rebuild 99dcfffd04SEd Maste everything and install it on the current system." Specifically, 100dcfffd04SEd Maste a reboot is required after installing the new kernel before 101dcfffd04SEd Maste installing world. 102b149eba4SEd Maste 103a25a1ff4SBrooks Davis20170424: 104a25a1ff4SBrooks Davis The NATM framework including the en(4), fatm(4), hatm(4), and 105a25a1ff4SBrooks Davis patm(4) devices has been removed.

Gerraty 609d1b06863SMark Murray Assuming you have 'device random' in your kernel config 610d1b06863SMark Murray file, the configurations allow a kernel option to override 611d1b06863SMark Murray this default. You may choose *ONE* of: 6126f78e390SSimon J. Gerraty 613d1b06863SMark Murray options RANDOM_YARROW # Legacy /dev/random algorithm. 614d1b06863SMark Murray options RANDOM_DUMMY # Blocking-only driver. 6156f78e390SSimon J. Gerraty 616d1b06863SMark Murray If you have neither, you get Fortuna. For most people, 617d1b06863SMark Murray read no further, Fortuna will give a /dev/random that works 618d1b06863SMark Murray like it always used to, and the difference will be irrelevant. 6196f78e390SSimon J. Gerraty 620d1b06863SMark Murray If you remove 'device random', you get *NO* kernel-processed 62102dcb6e0SEitan Adler entropy at all. This may be acceptable to folks building 622d1b06863SMark Murray embedded systems, but has complications. Carry on reading, 623d1b06863SMark Murray and it is assumed you know what you need. 624d1b06863SMark Murray 625d1b06863SMark Murray *PLEASE* read random(4) and random(9) if you are in the 62602dcb6e0SEitan Adler habit of tweaking kernel configs, and/or if you are a member 627d1b06863SMark Murray of the embedded community, wanting specific and not-usual 628d1b06863SMark Murray behaviour from your security subsystems. 629d1b06863SMark Murray 630d1b06863SMark Murray NOTE!! If you use RANDOM_DUMMY and/or have no 'device 631d1b06863SMark Murray random', you will NOT have a functioning /dev/random, and 632d1b06863SMark Murray many cryptographic features will not work, including SSH. 633d1b06863SMark Murray You may also find strange behaviour from the random(3) set 634d1b06863SMark Murray of library functions, in particular sranddev(3), srandomdev(3) 635d1b06863SMark Murray and arc4random(3). The reason for this is that the KERN_ARND 636d1b06863SMark Murray sysctl only returns entropy if it thinks it has some to 637d1b06863SMark Murray share, and with RANDOM_DUMMY or no 'device random' this 638d1b06863SMark Murray will never happen. 639d1b06863SMark Murray 640e44053b7SGregory Neil Shapiro20150623: 641e44053b7SGregory Neil Shapiro An additional fix for the issue described in the 20150614 sendmail 642e44053b7SGregory Neil Shapiro entry below has been been committed in revision 284717. 6436f78e390SSimon J.

This means that to 793143c11b4SDimitry Andric be able to successfully build the cross-tools stage of buildworld, with 794143c11b4SDimitry Andric clang as the bootstrap compiler, your system compiler or cross compiler 795143c11b4SDimitry Andric should either be clang 3.3 or later, or gcc 4.8 or later, and your 796143c11b4SDimitry Andric system C++ library should be libc++, or libdstdc++ from gcc 4.8 or 797143c11b4SDimitry Andric later. 798143c11b4SDimitry Andric 7990ac2c3d1SDimitry Andric On any standard FreeBSD 10.x or 11.x installation, where clang and 8000ac2c3d1SDimitry Andric libc++ are on by default (that is, on x86 or arm), this should work out 8010ac2c3d1SDimitry Andric of the box. 802143c11b4SDimitry Andric 803143c11b4SDimitry Andric On 9.x installations where clang is enabled by default, e.g. on x86 and 804143c11b4SDimitry Andric powerpc, libc++ will not be enabled by default, so libc++ should be 805143c11b4SDimitry Andric built (with clang) and installed first. If both clang and libc++ are 806143c11b4SDimitry Andric missing, build clang first, then use it to build libc++. 807143c11b4SDimitry Andric 808143c11b4SDimitry Andric On 8.x and earlier installations, upgrade to 9.x first, and then follow 809143c11b4SDimitry Andric the instructions for 9.x above. 810143c11b4SDimitry Andric 8110ac2c3d1SDimitry Andric Sparc64 and mips users are unaffected, as they still use gcc 4.2.1 by 8120ac2c3d1SDimitry Andric default, and do not build clang. 8130ac2c3d1SDimitry Andric 8140ac2c3d1SDimitry Andric Many embedded systems are resource constrained, and will not be able to 8150ac2c3d1SDimitry Andric build clang in a reasonable time, or in some cases at all. In those 8160ac2c3d1SDimitry Andric cases, cross building bootable systems on amd64 is a workaround. 8170ac2c3d1SDimitry Andric 818143c11b4SDimitry Andric This new version of clang introduces a number of new warnings, of which 819143c11b4SDimitry Andric the following are most likely to appear: 820143c11b4SDimitry Andric 821143c11b4SDimitry Andric -Wabsolute-value 822143c11b4SDimitry Andric 823143c11b4SDimitry Andric This warns in two cases, for both C and C++: 824143c11b4SDimitry Andric * When the code is trying to take the absolute value of an unsigned 825143c11b4SDimitry Andric quantity, which is effectively a no-op, and almost never what was 826143c11b4SDimitry Andric intended. The code should be fixed, if at all possible. If you are 827143c11b4SDimitry Andric sure that the unsigned quantity can be safely cast to signed, without 828143c11b4SDimitry Andric loss of information or undefined behavior, you can add an explicit 829143c11b4SDimitry Andric cast, or disable the warning. 830143c11b4SDimitry Andric 831143c11b4SDimitry Andric * When the code is trying to take an absolute value, but the called 832143c11b4SDimitry Andric abs() variant is for the wrong type, which can lead to truncation. 833143c11b4SDimitry Andric If you want to disable the warning instead of fixing the code, please 834143c11b4SDimitry Andric make sure that truncation will not occur, or it might lead to unwanted 835143c11b4SDimitry Andric side-effects. 836143c11b4SDimitry Andric 837143c11b4SDimitry Andric -Wtautological-undefined-compare and 838143c11b4SDimitry Andric -Wundefined-bool-conversion 839143c11b4SDimitry Andric 840143c11b4SDimitry Andric These warn when C++ code is trying to compare 'this' against NULL, while 841143c11b4SDimitry Andric 'this' should never be NULL in well-defined C++ code. However, there is 842143c11b4SDimitry Andric some legacy (pre C++11) code out there, which actively abuses this 843143c11b4SDimitry Andric feature, which was less strictly defined in previous C++ versions. 844143c11b4SDimitry Andric 845143c11b4SDimitry Andric Squid and openjdk do this, for example. The warning can be turned off 846143c11b4SDimitry Andric for C++98 and earlier, but compiling the code in C++11 mode might result 847143c11b4SDimitry Andric in unexpected behavior; for example, the parts of the program that are 848143c11b4SDimitry Andric unreachable could be optimized away. 849143c11b4SDimitry Andric 8500b327b63SRick Macklem20141222: 8510b327b63SRick Macklem The old NFS client and server (kernel options NFSCLIENT, NFSSERVER) 8520b327b63SRick Macklem kernel sources have been removed.

They were out of 967727a7ce8SJulio Merino sync because, when they were originally added to FreeBSD, the 968727a7ce8SJulio Merino upstream versions were not respected. These libraries are private 969727a7ce8SJulio Merino and not yet built by default, so renumbering them should be a 970727a7ce8SJulio Merino non-issue. However, unclean source trees will yield broken test 971727a7ce8SJulio Merino programs once the operator executes "make delete-old-libs" after a 972727a7ce8SJulio Merino "make installworld". 973727a7ce8SJulio Merino 9748c7ec47aSJulio Merino Additionally, the atf-sh binary was made private by moving it into 9758c7ec47aSJulio Merino /usr/libexec/. Already-built shell test programs will keep the 9768c7ec47aSJulio Merino path to the old binary so they will break after "make delete-old" 9778c7ec47aSJulio Merino is run. 9788c7ec47aSJulio Merino 979727a7ce8SJulio Merino If you are using WITH_TESTS=yes (not the default), wipe the object 980727a7ce8SJulio Merino tree and rebuild from scratch to prevent spurious test failures. 9818c7ec47aSJulio Merino This is only needed once: the misnumbered libraries and misplaced 9828c7ec47aSJulio Merino binaries have been added to OptionalObsoleteFiles.inc so they will 9838c7ec47aSJulio Merino be removed during a clean upgrade. 984727a7ce8SJulio Merino 98585d60e68SDimitry Andric20140512: 98685d60e68SDimitry Andric Clang and llvm have been upgraded to 3.4.1 release. 98785d60e68SDimitry Andric 988fa114234SWarner Losh20140508: 989fa114234SWarner Losh We bogusly installed src.opts.mk in /usr/share/mk. This file should 990fa114234SWarner Losh be removed to avoid issues in the future (and has been added to 991fa114234SWarner Losh ObsoleteFiles.inc). 992fa114234SWarner Losh 993a46954e2SWarner Losh20140505: 994a46954e2SWarner Losh /etc/src.conf now affects only builds of the FreeBSD src tree. In the 995a46954e2SWarner Losh past, it affected all builds that used the bsd.*.mk files. The old 996a46954e2SWarner Losh behavior was a bug, but people may have relied upon it. To get this 997a46954e2SWarner Losh behavior back, you can .include /etc/src.conf from /etc/make.conf 998a46954e2SWarner Losh (which is still global and isn't changed). This also changes the 999a46954e2SWarner Losh behavior of incremental builds inside the tree of individual 100059a24370SWarner Losh directories. Set MAKESYSPATH to ".../share/mk" to do that. 1001a46954e2SWarner Losh Although this has survived make universe and some upgrade scenarios, 100255b76981SWarner Losh other upgrade scenarios may have broken. At least one form of 100355b76981SWarner Losh temporary breakage was fixed with MAKESYSPATH settings for buildworld 100459a24370SWarner Losh as well... In cases where MAKESYSPATH isn't working with this 100559a24370SWarner Losh setting, you'll need to set it to the full path to your tree. 1006a46954e2SWarner Losh 1007bd871f14SWarner Losh One side effect of all this cleaning up is that bsd.compiler.mk 1008bd871f14SWarner Losh is no longer implicitly included by bsd.own.mk. If you wish to 1009bd871f14SWarner Losh use COMPILER_TYPE, you must now explicitly include bsd.compiler.mk 1010bd871f14SWarner Losh as well. 1011bd871f14SWarner Losh 1012461dbce2SEitan Adler20140430: 1013461dbce2SEitan Adler The lindev device has been removed since /dev/full has been made a 1014461dbce2SEitan Adler standard device. __FreeBSD_version has been bumped. 1015461dbce2SEitan Adler 1016e9aba509SEnji Cooper20140424: 1017e9aba509SEnji Cooper The knob WITHOUT_VI was added to the base system, which controls 1018e9aba509SEnji Cooper building ex(1), vi(1), etc. Older releases of FreeBSD required ex(1) 1019e9aba509SEnji Cooper in order to reorder files share/termcap and didn't build ex(1) as a 1020e9aba509SEnji Cooper build tool, so building/installing with WITH_VI is highly advised for 1021e9aba509SEnji Cooper build hosts for older releases. 1022e9aba509SEnji Cooper 1023e9aba509SEnji Cooper This issue has been fixed in stable/9 and stable/10 in r277022 and 1024e9aba509SEnji Cooper r276991, respectively. 1025e9aba509SEnji Cooper 10262bb08298SWarner Losh20140418: 10272bb08298SWarner Losh The YES_HESIOD knob has been removed.

Previously the uart(4) driver prevented 10344c710b67SMarcel Moolenaar any process from changing the baudrate or the CLOCAL and HUPCL 10354c710b67SMarcel Moolenaar control flags. By removing the restrictions, operators can make 10364c710b67SMarcel Moolenaar changes to the serial console port without having to reboot. 10374c710b67SMarcel Moolenaar However, when getty(8) is started on the serial device that is 10384c710b67SMarcel Moolenaar associated with the low-level console, a misconfigured terminal 10394c710b67SMarcel Moolenaar line in /etc/ttys will now have a real impact. 10404c710b67SMarcel Moolenaar Before upgrading the kernel, make sure that /etc/ttys has the 10414c710b67SMarcel Moolenaar serial console device configured as 3wire without baudrate to 1042086036aaSMarcel Moolenaar preserve the previous behaviour.

Gerraty 1302ff8d4375SSimon J. Gerraty It is worth noting that bmake (like gmake) treats the command 1303ff8d4375SSimon J. Gerraty line as the unit of failure, rather than statements within the 1304ff8d4375SSimon J. Gerraty command line. Thus '(cd some/where && dosomething)' is safer 1305ff8d4375SSimon J.

The most disruptive API change is to 1557d1675e38SJason Evans /etc/malloc.conf. If your system has an old-style /etc/malloc.conf, 1558d1675e38SJason Evans delete it prior to installworld, and optionally re-create it using the 1559d1675e38SJason Evans new format after rebooting. See malloc.conf(5) for details 1560d1675e38SJason Evans (specifically the TUNING section and the "opt.*" entries in the MALLCTL 1561d1675e38SJason Evans NAMESPACE section). 1562d1675e38SJason Evans 156384db023eSJuli Mallett20120328: 156484db023eSJuli Mallett Big-endian MIPS TARGET_ARCH values no longer end in "eb". mips64eb 156584db023eSJuli Mallett is now spelled mips64. mipsn32eb is now spelled mipsn32. mipseb is 156684db023eSJuli Mallett now spelled mips.

Previously 1578c7e41c8bSMikolaj Golub nullfs(5) did not pass through all behaviours to the underlying layer, 1579c7e41c8bSMikolaj Golub as a result if we bound to a socket on the lower layer we could connect 1580c7e41c8bSMikolaj Golub only to the lower path; if we bound to the upper layer we could connect 1581c7e41c8bSMikolaj Golub only to the upper path. The new behavior is one can connect to both the 1582c7e41c8bSMikolaj Golub lower and the upper paths regardless what layer path one binds to. 1583c7e41c8bSMikolaj Golub 1584ca1672daSBjoern A.

While generally safe, there are 1644456b5dd8SWarner Losh sometimes problems using -j to upgrade. If your upgrade fails with 16451733d35cSRuslan Ermilov -j, please try again without -j. From time to time in the past there 1646456b5dd8SWarner Losh have been problems using -j with buildworld and/or installworld. This 1647456b5dd8SWarner Losh is especially true when upgrading between "distant" versions (eg one 1648456b5dd8SWarner Losh that cross a major release boundary or several minor releases, or when 1649456b5dd8SWarner Losh several months have passed on the -current branch). 1650a24eff53SWarner Losh 16515780f3baSWarner Losh Sometimes, obscure build problems are the result of environment 16525780f3baSWarner Losh poisoning. This can happen because the make utility reads its 1653456b5dd8SWarner Losh environment when searching for values for global variables. To run 1654456b5dd8SWarner Losh your build attempts in an "environmental clean room", prefix all make 1655456b5dd8SWarner Losh commands with 'env -i '. See the env(1) manual page for more details. 16565780f3baSWarner Losh 16575ad05815SWarner Losh When upgrading from one major version to another it is generally best to 16585ad05815SWarner Losh upgrade to the latest code in the currently installed branch first, then 16595ad05815SWarner Losh do an upgrade to the new branch. This is the best-tested upgrade path, 16605ad05815SWarner Losh and has the highest probability of being successful. Please try this 16615ad05815SWarner Losh approach if you encounter problems with a major version upgrade. Since 16625ad05815SWarner Losh the stable 4.x branch point, one has generally been able to upgade from 16635ad05815SWarner Losh anywhere in the most recent stable branch to head / current (or even the 16645ad05815SWarner Losh last couple of stable branches). See the top of this file when there's 16655ad05815SWarner Losh an exception. 1666081ff8acSDoug Barton 16676eeab389SWarner Losh When upgrading a live system, having a root shell around before 1668da0e842aSWarner Losh installing anything can help undo problems. Not having a root shell 1669da0e842aSWarner Losh around can lead to problems if pam has changed too much from your 1670da0e842aSWarner Losh starting point to allow continued authentication after the upgrade. 1671da0e842aSWarner Losh 16729c80b8aaSWarner Losh This file should be read as a log of events.

At this point in the life 1783fdb9f54dSWarner Losh cycle of current, things change often and you are on your own 1784fdb9f54dSWarner Losh to cope. The defaults can also change, so please read ALL of 1785fdb9f54dSWarner Losh the UPDATING entries. 1786ba26da8eSWarner Losh 17871dece4a9SWarner Losh Also, if you are tracking -current, you must be subscribed to 17881dece4a9SWarner Losh freebsd-current@freebsd.org. Make sure that before you update 17891dece4a9SWarner Losh your sources that you have read and understood all the recent 17901dece4a9SWarner Losh messages there. If in doubt, please track -stable which has 17911dece4a9SWarner Losh much fewer pitfalls. 17921dece4a9SWarner Losh 1793134d2e86SWarner Losh [1] If you have third party modules, such as vmware, you 1794134d2e86SWarner Losh should disable them at this point so they don't crash your 1795134d2e86SWarner Losh system on reboot. 1796134d2e86SWarner Losh 1797ee6e1fc3SWarner Losh [3] From the bootblocks, boot -s, and then do 1798ee6e1fc3SWarner Losh fsck -p 1799ee6e1fc3SWarner Losh mount -u / 1800ee6e1fc3SWarner Losh mount -a 18016586253aSWarner Losh cd src 180247d0d01fSWarner Losh adjkerntz -i # if CMOS is wall time 1803f6a0ef01SWarner Losh Also, when doing a major release upgrade, it is required that 1804f6a0ef01SWarner Losh you boot into single user mode to do the installworld. 1805ee6e1fc3SWarner Losh 1806a6cd4f9dSWarner Losh [4] Note: This step is non-optional. Failure to do this step 1807a6cd4f9dSWarner Losh can result in a significant reduction in the functionality of the 1808a6cd4f9dSWarner Losh system. Attempting to do it by hand is not recommended and those 1809a6cd4f9dSWarner Losh that pursue this avenue should read this file carefully, as well 1810a6cd4f9dSWarner Losh as the archives of freebsd-current and freebsd-hackers mailing lists 181150e8eca6SDoug Barton for potential gotchas. The -U option is also useful to consider. 181250e8eca6SDoug Barton See mergemaster(8) for more information. 1813a6cd4f9dSWarner Losh 1814835284beSWarner Losh [5] Usually this step is a noop. However, from time to time 1815835284beSWarner Losh you may need to do this if you get unknown user in the following 1816835284beSWarner Losh step. It never hurts to do it all the time. You may need to 1817835284beSWarner Losh install a new mergemaster (cd src/usr.sbin/mergemaster && make 1818835284beSWarner Losh install) after the buildworld before this step if you last updated 181920e0cc0aSBrooks Davis from current before 20130425 or from -stable before 20130430. 1820835284beSWarner Losh 182194877c06SAlexander Leidinger [6] This only deletes old files and directories. Old libraries 182294877c06SAlexander Leidinger can be deleted by "make delete-old-libs", but you have to make 182394877c06SAlexander Leidinger sure that no program is using those libraries anymore. 182494877c06SAlexander Leidinger 1825456b5dd8SWarner Losh [8] In order to have a kernel that can run the 4.x binaries needed to 1826456b5dd8SWarner Losh do an installworld, you must include the COMPAT_FREEBSD4 option in 1827456b5dd8SWarner Losh your kernel. Failure to do so may leave you with a system that is 1828456b5dd8SWarner Losh hard to boot to recover. A similar kernel option COMPAT_FREEBSD5 is 1829456b5dd8SWarner Losh required to run the 5.x binaries on more recent kernels. And so on 1830456b5dd8SWarner Losh for COMPAT_FREEBSD6 and COMPAT_FREEBSD7. 1831c74fe6afSWarner Losh 1832e5dc5f61SWarner Losh Make sure that you merge any new devices from GENERIC since the 1833e5dc5f61SWarner Losh last time you updated your kernel config file. 1834e5dc5f61SWarner Losh 183521c075eaSWarner Losh [9] When checking out sources, you must include the -P flag to have 1836e5dc5f61SWarner Losh cvs prune empty directories. 1837e5dc5f61SWarner Losh 1838e5dc5f61SWarner Losh If CPUTYPE is defined in your /etc/make.conf, make sure to use the 1839e5dc5f61SWarner Losh "?=" instead of the "=" assignment operator, so that buildworld can 1840e5dc5f61SWarner Losh override the CPUTYPE if it needs to. 1841e5dc5f61SWarner Losh 1842e5dc5f61SWarner Losh MAKEOBJDIRPREFIX must be defined in an environment variable, and 1843e5dc5f61SWarner Losh not on the command line, or in /etc/make.conf. buildworld will 1844e5dc5f61SWarner Losh warn if it is improperly defined. 1845dc0dbf5cSWarner LoshFORMAT: 1846dc0dbf5cSWarner Losh 1847f699bbbbSMark OvensThis file contains a list, in reverse chronological order, of major 1848630f2154SGlen Barberbreakages in tracking -current.
