 20021003:  20090110:
         Several changes have been made to the autoconfiguration          time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
         framework.  Users must update and reinstall usr.sbin/config          1. Make sure your kernel has COMPAT_50 in it. Build and install.
         before building a new kernel.          2. make sure build.sh completes and the binaries in a chroot work
              before installing.
 20020922:          3. If you don't use build.sh and you build directly to root, and
         MKDYNAMICROOT=yes enabled by default, which means that             your build breaks in the middle, don't despair. Make sure headers
         certain shared libraries are installed into /lib, the shared             are installed properly, and start building libraries first libc
         linker is installed into /libexec, and all programs in /bin             and libutil, install them and then continue building all the
         and /sbin are dynamically linked.             libraries in src/lib and src/gnu/lib and install them. Once
         If you do not use "make build", you should ensure that             the new libraries are installed, you can restart the build.
         you have the libraries and shared linker in the new locations,          4. If you compile packages and you notice link time warnings,
         with:             you'll need to bump them and rebuild them.
                 make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so          5. Next time you run pwd_mkdb with the new binary, the file
              will be upgraded and it will not be backwards compatible.
 20020917:          6. The utmpx/wtmpx files have been versioned, and there is
         USE_NEW_TOOLCHAIN has been replaced with:             a heuristic for utmp. You are better off removing the
             -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which             old files after upgrading.
                 there is no working in-tree toolchain (hppa, ns32k, sh5,

                 enables the cross-build framework even for TOOLCHAIN_MISSING          (done automatically by build.sh) and then you need to rerun
                 platforms.          config on all kernel configuration files before rebuilding those
         gehenna-devsw has been merged into the trunk. Need to update and  20081205:
         reinstall usr.sbin/config before build the kernel.          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
 20020822:          set and will appear as extra files for MKX11=no update builds.
         Crunched rescue tools (contents of /bin and /sbin, plus others)  
         are now provided in /rescue.  20081122:
           On i386, various kernel options(4) in GENERIC including

         from sources newer than 20020820 (see the next entry).          following files as well as a new GENERIC kernel:
 20020820:          - build and install kernel modules from src/sys/modules
         crunchgen(1) changed to ensure that the generated program  
         is statically linked.          - install the latest bootloader, which will load a module
             for the file system from which the kernel is loaded automatically
         Solution: update and reinstall usr.bin/crunch

         Add the following into /etc/group:          If you built and installed a libc from sources between
           2008/08/20 and 2008/08/26 you got a broken strtouq(3)
         sshd:*:16:          which results in false errors reported by lint(1).
           Since this breaks the libc build itself, manual help is
         and the following to /etc/master.passwd (via vipw):          needed -- lint must be disabled temporarily, e.g.:
             $ (cd lib/libc && make MKLINT=no dependall install)
         sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin  
         also /var/chroot/sshd directory needs to be present (digged as a part of          MKDEBUG build was broken because the .depend files did not know
         build process).          about .go files. You need to remove all .depend files and rebuild.
 20020426:  20080731:
         NBUILDJOBS obsoleted in favor of just using -j.          WAPBL (metadata journaling support) has been added, but at this
           time isn't backwards compatible with pre-WAPBL aware kernels

 20020311:            $ (cd sys/sys/ && nbmake-$arch includes)
         ssh configuration files were moved from /etc to /etc/ssh.  Beware            $ (cd sbin/drvctl/ && nbmake-$arch clean)
         if you restart your machine from remote.  Note that sshd.conf needs            $ (cd sbin/drvctl/ && nbmake-$arch all)
         to be changed (due to the use of "/etc" inside).  
           leaves new drvctl utility in sbin/drvctl build directory.
         Users of the VAX port will need to rebuild and install gas  20080503:
         so it deal with the now present register prefix used in all          The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
         the VAX assembly files.  
 20020118:          For a while, unprivileged UPDATE builds would fail to
           succeed at the checkflist stage, complaining that
         ntpd user/group has been added.  Need to hand add this in or builds          ${DESTDIR}/stand/<arch>/ did not exist.  A fix for this
         will break as mtree aborts early.          problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
           If you already hit this problem, update the .mk file,
         Add the following into /etc/group:          remove ${DESTDIR}/stand/<arch>, and re-run the build.
         ntpd:*:15:  20080303:
           Linker warnings are now fatal if $WARNS>0.
         and the following to /etc/master.passwd (via vipw):  
         ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin          The posix_fadvise system call has been changed from an assembly
           stub, to a c file that calls an assembly stub. You need to
 20011207:          'rm -f posix_fadvise.* .depend' in the libc build directory to
           avoid using the old assembly stub.
         If you're attempting to build a snapshot on sparc64 and are getting  
         reloc errors from the toolchain groff binary this means your native  20071209:
         toolchain has some broken C++ bits.          The acpiec(4) driver has been split into two attachments. If you
           get ACPI errors before the attachment, please update your kernel
         To fix:          configuration file appropriately or see GENERIC for more details.
         Build a new toolchain (i.e. build.sh -t)  20071115:
         Use the new toolchain to build and install natively (i.e. /usr/lib)          The it(4) driver has been renamed to itesio(4) and the old port
           argument specified in the kernel configuration file is not valid
         gnu/lib/libgcc          anymore. The itesio(4) driver now uses the Super I/O address port
         gnu/lib/libstdc++          rather than the EC address port. Please update your kernel
           configuration file appropriately or see GENERIC for more details.
         After this a snapshot will be able to be built.  
 20011201:          The pccons(4) driver has been removed from the NetBSD/shark port.
         In order for a sparc64 build to work you must have a working awk. If          You need to update any custom kernel configuration file you have
         you've built and installed a system with the new toolchain up to this          to remove any references to pccons (which includes removing the
         point you do not have a working awk as its ability to do floating          now useless XSERVER option) and replace them with the correct
         point is broken.          entries for the wscons driver.  See the GENERIC configuration file
           for more details.
         To build:  
         remake and install gnu/lib/libgcc          A latent bug in dhclient/dhcpd that caused it to be unable to
         remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links          enumerate interfaces was fixed.  The bug began to cause
         against the new libgcc.a)          problems after 20070911 when the kernel's SIOCGIFCONF
           implementation was repaired.  From 20070529 to 20070911 racoon
 20011128:          could not enumerate interfaces.  (These are noted because
         Kernel config information was changed to use defflag in          normal kernel/userspace version matching hygiene is not
         the various "files" files.  Bug fixes to config(8) are          sufficient to avoid this problem.)  Ensure that both kernel

         to build and install in usr.sbin/config before attempting  
         to build a new kernel.  20070703:

         before building libc.  
 20011029:          The way OS emulations lookup filenames inside the emulation root
         The new document BUILDING.mdoc (view with nroff | more, or          has been changed.  Rather than modify the pathname (and copy back
         see pre-generated .txt and .html versions) describes the build          to userspace) namei() and lookup() directly check the emulation

         UPDATING for these systems, as tool updating is taken care of  
         by the new build system.  20070412:

         Crunchgen has been updated to work via reach-over makefiles. Updating  
         is suggested before running a snapshot build  20070209:
           The threading model was changed when the newlock2 branch

           is the only threaded application in the base system.
         grep.info is now built from grep.texi using makeinfo.  Since it  20061214:
         requires makeinfo v4.0, you need to install new texinfo before          Following the move of string_to_flags() and flags_to_string()
         building gnu/usr.bin/grep.  To install new texinfo, please follow          from the bin/ls/ sources to libutil, users doing UPDATE builds
         the instruction described in 20010726 entry.          will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
 20010803:                  bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
         (i386 only): i386 kernel now uses new instructions like                  usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
         `fxsave' which old gas doesn't understand.  To build the                  as the installation images in distrib/
         kernel successfully, you need to build and install a new toolchain,          in order to excise stale references to the old stat_flags.h header
         (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"          file in the ls sources -- stat_flags.h has been removed.
         from your kernel configuration until you rebuild your userland.  
         See 20011029 above and BUILDING file in this directory for more information.  20061108:
         [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]          The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
 20010731:          does not depend on -lssp and -lssp-nonshared. You'll need to
         Bootloader update on ELF platforms.  DDB in kernels from before          make clean in src/tools/gcc first to rebuild the compiler.
         this will be unable to read symbol tables provided by newer  
         bootloaders.  20061009:
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
 20010726:          available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
         Texinfo was updated to 4.0.  To avoid failures when trying to  
         build the included texinfo files, do:  20060814:
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
         cd src/gnu/usr.bin/texinfo          withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
         make MKINFO=no dependall install          kernel configuration for an example.  X servers from the last
           few years should cope.
         Enabled correct .init/.fini processing in crt0.  The way this  20060703:
         was done was to change a -I directive to cc(1), which means          MPACPI is no more. We always configure PCI interrupts using ACPI
         make(1) will have a stale dependency (it will be checking the          if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
         timestamp on the wrong "dot_init.h").          to ACPI_SCANPCI. Thanks to work from fvdl.
         The symptom you will see is that new programs die with SIGSEGV  20060627:
         if you have a stale dependency.          socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
         Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so          your kernel has 'options COMPAT_30' set, or else 'bad system call'
         before starting your build.          errors will result.
         A construct was added to uvm_page.h that uncovered a bug  
         in lint(1).  If you get a warning/error about a non-portable  
         bitfield, update your lint(1) before proceeding.  
         Added named user/group to system. Need to hand add this in or builds  
         will break as mtree aborts early.  
         To work around add by hand:  
         to /etc/group and add:  
         named:*:14:14::0:0:Named pseudo-user:/var/named:/sbin/nologin  
         to master.passwd (use vipw for instance if doing by hand).  
         Now a make build should progress.  
         get/setprogname() added. Any hostprogs that may use this will need  
         to be bootstrapped manually until the host system is current.  
         Known problems: sys/arch/macppc/stand/fixcoff  
                         usr.sbin/config (adding -DMAKE_BOOTSTRAP to

         prepare the code to compile with stricter gcc flags. in  
         particular start eliminating redundant declarations. Yacc  
         needs to be installed before make build.  
         introduce .if commands(target) in make(1). You need to  
         bring everything up-to-date first, then without installing  
         anything make and install in usr.bin/make, then proceed  
         with make build.  
         bsd.subdir.mk committed 20001230 had a bug which caused

         New share/mk files needed to support .WAIT in SUBDIR variables.  
         If you get make errors,  
                 (cd share/mk; make install)  
         Also, PRINTOBJDIR has changed and is now used more heavily.  
         The `ca' device driver has been replaced by `ld'; although the  
         major and minor numbers haven't changed, you should update your /dev  
         The following make directives are obsoleted.  
         By default, RSA is built into libcrypto.  IDEA and RC5 will not be
