The line "pseudo-device rnd" should be + removed from any custom kernel config files users may have. + +20111119: + A problem with the datastructures used by the rndctl(8) + utility (pointers in datastructures in an array, making 32->64 + bit compatibility very painful) has been fixed in a + non-backwards-compatible way. If you replace your kernel, + replace your rndctl executable too. + +20111001: + the prop_*_send_syscall() functions from proplib(3) have been + changed and their new version is not backward compatible with the old + one.

Best to delete both objdir and + DESTDIR before running this update. So far, only the + sparc64, mips and powerpc platforms have changed. + +20110803: + The layout of external/public-domain/xz has changed. To do an + update build you will have to remove the contents of the OBJDIR + for external/public-domain/xz/bin by hand as the xz entry there + is now a directory. + +20110410: + The configuration of src/tools/gcc has changed. To do an + update build you have to clean both tools/binutils and + tools/gcc by hand. + +20110328: + Building the Xorg binary was moved into a subdirectory to fix + ordering issues with "make all". It may be necessary to remove + the OBJDIR for external/mit/xorg/server/xorg-server/hw/xfree86 + if your update build fails, as the "Xorg" entry there is now a + directory. + +20110121: + Assembler files no longer use -traditional-cpp. This can break + the build of individual parts of the tree. This is handled + correctly by build.sh. Manual builds have to update /usr/share/mk + and re-run config(1) for any kernel configurations as needed. + +20101217: + The tcpdump(8) program was changed to drop privileges and chroot(2) + by default. It may be necessary to manually update passwd(5) and + group(5) in order to make the program work with existing setups. + +20101125: + The latest changes to setenv(3) dissallow setting environment + variables with names that contain '='. Revision 1.18 of env.c + assumed that this was allowed. Installing a new libc with an + old copy of /usr/bin/env causes env x=1 printenv | grep x= to + break which affects the autoconf tests for dependency finding, + so building gcc will end up printing: + checking dependency style of gcc... none + configure: error: no usable dependency style found + Fix it by rebuilding and re-installing env. + +20101119: + Recent Xorg updates in xsrc/external/mit/ may cause various build + or run-time problems.

Please + remove usr/X11R7/lib/X11/xkb/compiled from your $DESTDIR. + +20100222: + The shared objects file extension has been changed from .so to + .pico, in order to avoid conflicts with shared libraries names + libXX.so. All now stale regular .so files can be removed from + your object directories. + +20100204: + The termcap database has been removed from the sources, + but has not been marked obsolete so it is not removed + from the system when upgrading. + As such, you will need to remove them from your object + and destination directories. + +20091101: + After updating, it may be necessary to make the 'cleandir' + target in src/tools/yacc/ and in src/usr.bin/yacc/ before a + 'build.sh -u tools' or 'build.sh -u distribution'. Ditto + src/tools/lex/ and src/usr.bin/lex/. + +20091001: + On amd64 you must rebuild tools (to get the new binutils) + before building a kernel, or the build fails on cpufunc.S. + +20091001: + An error will create a ./usr/X11R7/lib/X11/xkb/compiled/xkb + symlink, failing the build.

Update build of libc.a (and libc_pic.a) + may fail because the archive contains the unwanted index.o. + (Similarly for strrchr() and rindex().) + +20090709: + Native Xorg was upgraded again. Builds will probably fail again + without a clean objdir, at least for src/external/mit/xorg. + +20090616: + Native Xorg was upgraded. Builds will need a clean objdir for + src/external/mit/xorg. Upgrading a system from sets will not + work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc + subdirectory has been changed into a file, and this needs to + be manually "rm -r"'ed before installing xbase.tgz. + +20090501: + Several new functions were added to string.h/libc, and this + can cause autoconf problems during the tool build for people + who fail to clean out their tools objects properly. If you + note messages about stpcpy, stpncpy or strnlen accompanying a + failure during the tool build, clean out all your tools + objects and start again. + +20090325: + The i386 port was switched to i486 default toolchain. This requires + cleaning your src/tools directory and $TOOLDIR and rebuilding them. + +20090126: + The __posix_fadvise50 system call changed assembly stub type. You + need to 'rm -f __posix_fadvise50.*' in the libc build directory + to avoid using the old assembly stub. + +20090202: + pkg_install now depends on the pkgdb cache for automatic conflict + detection. It is recommented to rebuild the cache with + ``pkg_admin rebuild''. + +20090110: + time_t and dev_t have been bumped to 64 bit quantities. To upgrade: + 1. Make sure your kernel has COMPAT_50 in it. Build and install. + This is needed even in the MODULAR kernel because there is + conditionally compiled code in rtsock.c. + 2. make sure build.sh completes and the binaries in a chroot work + before installing. + 3. If you don't use build.sh and you build directly to root, and + your build breaks in the middle, don't despair. Make sure headers + are installed properly, and start building libraries first libc + and libutil, install them and then continue building all the + libraries in src/lib and src/gnu/lib and install them. Once + the new libraries are installed, you can restart the build. + 4. If you compile packages and you notice link time warnings, + rebuild the required packages to update their shared libraries. + Any package you rebuild will require rebuilding all the packages + that depend on it. + 5. Next time you run pwd_mkdb with the new binary, the file + will be upgraded and it will not be backwards compatible. + 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see + lastlogx(5)) have been versioned, and there is a heuristic + for utmp. You are better off removing the old files after + upgrading. The automated clearing of /var/run during + boot, and the automated rotating of files in /var/log by + newsyslog(8), may mean that you do not have to remove the + files manually. + 7. The optional accounting file (/var/account/acct, see + accton(8)) has not been versioned, and will need to be + removed. The automatic rotation of the accounting file by + /etc/daily limits the bad consequences of failure to remove + the file. + 8. Application software that writes time_t to binary files on + disk will break or need attention. Most notably: if you are + using PostgreSQL < 8.4, you need to dump your databases, + rebuild PostgreSQL with the new time_t, then restore. + +20081219: + config(1) has been updated, and one of the files it creates - + swapnetbsd.o - has changed format. You need to rebuild config + (done automatically by build.sh) and then you need to rerun + config on all kernel configuration files before rebuilding those + kernels. + +20081205: + If you build with MKX11=no, you should remove /etc/rc.d/xdm and + /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc + set and will appear as extra files for MKX11=no update builds. + +20081122: + On i386, various kernel options(4) in GENERIC including + file systems have been disabled and moved into kernel modules. + Before trying a new GENERIC kernel, you have to prepare the + following files as well as a new GENERIC kernel: + + - build and install kernel modules from src/sys/modules + + - install the latest bootloader, which will load a module + for the file system from which the kernel is loaded automatically + + If you have to load your kernel from a file system which is not of + the same type as the root file system, you have to load the necessary + file system module manually on the boot prompt or in the boot.cfg file. + +20080827: + If you built and installed a libc from sources between + 2008/08/20 and 2008/08/26 you got a broken strtouq(3) + which results in false errors reported by lint(1). + Since this breaks the libc build itself, manual help is + needed -- lint must be disabled temporarily, e.g.: + $ (cd lib/libc && make MKLINT=no dependall install) + +20080813: + MKDEBUG build was broken because the .depend files did not know + about .go files.
