 This file is intended to be a brief introduction to the build  This file (UPDATING) is intended to be a brief reference to recent
 process and a reference on what to do if something doesn't work.  changes that might cause problems in the build process, and a guide for
   what to do if something doesn't work.
   For a more detailed description of the recommended way to build NetBSD
   using build.sh, see the BUILDING file.
   Note that much of the advice in this UPDATING file was written before
   build.sh existed.  Nevertheless, the advice here may be useful for
   working around specific problems with build.sh.
 For a more detailed description see Makefile.  See also: BUILDING, build.sh, Makefile.
 Recent changes:  Recent changes:
 ^^^^^^^^^^^^^^^  ^^^^^^^^^^^^^^^
           The pckbc driver on sgimips IP32 has been removed. Use macekbc
           instead. See the GENERIC32_IP3x kernel configuration for an
           src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
           on many platforms due to incorrect flags settings.  If you
           updated and built after about 20070315, do "nbmake-$arch
           cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
           rebuild of object files that might have been built
           incorrectly, and ensure that you have at least
           src/lib/libc/Makefile 1.130.
           src/sys/sys/{sa.h,savar.h} were removed.
             find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
                 | xargs egrep -l '/sa.h|/savar.h' | xargs rm
           will allow dependencies on those files to get get rebuilt
           The threading model was changed when the newlock2 branch
           was merged to NetBSD-current.  If you boot with a new
           kernel (version 4.99.10), then you also need a new pthread
           library (/usr/lib/libpthread.so.0.7).  If you boot with
           an old kernel, then you need the old pthread library
           (/usr/lib/libpthread.so.0.6).  Provided you keep the kernel and
           the pthread library in sync, old threaded applications should
           continue to work with an old or new kernel.  Note that named(8)
           is the only threaded application in the base system.
           Following the move of string_to_flags() and flags_to_string()
           from the bin/ls/ sources to libutil, users doing UPDATE builds
           will need to do a "make cleandir" in
                   tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
                   bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
                   usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
                   as the installation images in distrib/
           in order to excise stale references to the old stat_flags.h header
           file in the ls sources -- stat_flags.h has been removed.
           The configure script used in the src/tools/gcc compiler has been
           changed to indicate that our libc has ssp support built-in and
           does not depend on -lssp and -lssp-nonshared. You'll need to
           make clean in src/tools/gcc first to rebuild the compiler.
           The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
           available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
           The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
           withdrawn.  Use vidcvideo and pckbd instead.  See the GENERIC
           kernel configuration for an example.  X servers from the last
           few years should cope.
           MPACPI is no more. We always configure PCI interrupts using ACPI
           if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
           to ACPI_SCANPCI. Thanks to work from fvdl.
           socket(2) has changed, and its system call has been versioned.
           For userlands with the old version of socket(2), make sure that
           your kernel has 'options COMPAT_30' set, or else 'bad system call'
           errors will result.
           The kernel linker scripts for i386 and xen
           (sys/arch/i386/conf/kern.ldscript*) were changed to set the
           load address correctly, for the benefit of MULTIBOOT boot loaders
           (like Grub). If you use a linker (ld) older than from 2006/04/17, it
           will be unable to link the kernel because of a bug and ld will fail
           with an error like:
               ../../../../arch/i386/conf/kern.ldscript:45 \
                   non constant expression for load base
           You need to update at least src/gnu/dist/binutils/ld and recompile
           and install the linker. If using the build.sh script, the easiest
           way is with a "build.sh tools" command, with any other options
           that you use normally. When using build.sh, the linker binary is
           installed as ${TOOLDIR}/bin/i386--netbsdelf-ld.
           the protocol between the sparc64 bootloader (ofwboot) and
           the kernel was changed. Before installing a new kernel,
           you need to update ofwboot. After a full build, just copy
           /usr/mdec/ofwboot to /, or do a rebuild of
           src/sys/arch/sparc/stand/ofwboot and install the result to /.
           arch/*/conf/std.* was changed to include conf/std, which
           contains MI options previously enabled by default.
           If you have kernel config files which doesn't include
           arch/*/conf/std.*, you need to edit them to include conf/std
           to get the previous configuration.
           named.conf was moved from /etc/namedb to /etc.
           postinstall(8) migrates this during interactive use.
           Users of MKUPDATE=yes will need to manually rectify
           this in their DESTDIR.
           Some data structures in sys/device.h, related to interface
           attributes and locator names, were changed. config(1) was
           modified to emit the new data structures.
           Thus usr.bin/config must be updated (and run on the kernel
           configuration file) before a new kernel can be built.
           genassym.sh(8) was moved to genassym(1). You need to either build
           tools first or install the version of genassym from /usr/bin before
           you can build a kernel again.
           Because a kernfs bug which xentools relies on was fixed,
           xentools up to xentools20-2.0.3nb4 won't work with new kernel.
           postinstall(8) was moved from /etc to /usr/sbin and made part
           of the "base" set, to make it easier to invoke after an
           pcppi(4) was separated in two devices, adding attimer(4).  Be sure
           to add a config line for an attimer(4) device in your kernel
           configuration, or you won't be able to set the pitch of the beep
           with wsconsctl.  Depending on the default value for the pitch, you
           might even not hear any more beep.  Also, it is advised to attach both
           devices the same way (i.e., both on isa or both on acpi) or the
           pcppi(4) device may fail to find the attimer(4) one.
           Fixes to tools/Makefile.gnuhost may cause UPDATE=1 builds in
           some of the cross tools to fail if they use configure. Some configure's
           cache the environment passed in and notice the new environment is
           different and abort. Doing a clean in tools/ should be enough to
           make a build continue.
           Since su is using pam by default now, make sure that you have
           /etc/pam.d populated (postinstall will do that automatically
           for you). Otherwise su will fail open (i.e. will not require
           a password).
           Make had a path resolution bug that manifested itself as not
           being able to install openpam.3. This bug has been fixed, but
           you might need to rebuild make manually first to get through
           the build.
           Userland programs have been changed to use /dev/bpf instead of
           /dev/bpfX. You need to create that device by installing a new
           MAKEDEV and running it, or mv /dev/bpf0 /dev/bpf && rm /dev/bpf[0-9]*
           A bug was introduced into /bin/sh (var.c rev 1.35) which causes
           variables to not export correctly to subshells in all cases. This
           will cause builds to break if that version of /bin/sh is installed
           on the system. The proper version of /bin/sh can be verified with:
           ident /bin/sh | grep var
           Any /bin/sh w. version 1.35 will not work and needs to be updated
           before attempting a build.
           The ipfilter kernel sources moved from sys/netinet to
           dist/sys/ipf/netinet. Due to the move some Makefile
           dependencies are now dangling requiring a make cleandir
           before they work again (kdump, ktruss, rescue, ipf, and
           ftp-proxy are the victims).
           The rc.d/sendmail script now uses a heuristic to determine
           if sendmail should be started at boot time.  It checks the
           contents of /etc/mailer.conf, /etc/mail/submit.cf, and the
           owner and mode of the sendmail binary to see if any changes
           to the mail infrastructure have been made.  If no changes
           are detected, it will start an SMTP listener.
           Setting sendmail=NO in /etc/rc.conf will override this.
           If you are only using sendmail by default and only for
           local delivery, it is important that you also update your
           sendmail.cf so that the SMTP listener only listens on the
           loopback interface.
           The method by which athhal-elf.o gets pulled into i386
           kernel builds has been changed again.  The latest version
           of bsd.files.mk is no longer required.
           Due to the recent rototill of tools/compat it's crucial one starts
           from a clean objdir under tools/*.
           This is mostly due to generated files (yacc and lex sources) needing
           to be generated with new rules from bsd.hostprog.mk.
           The safest course is to rm -rf all objects under tools before building.
           The end-user modifiable X11 configuration has been moved
           from /usr/X11R6/lib/X11/<dir> to /etc/X11/<dir>.
           Ensure that src and xsrc is up to date, and run
           "make cleandir" in src/x11 before your next build.
           postinstall currently doesn't migrate the files from
           /usr/X11R6/lib/X11/* to /etc/X11/* although it does
           detect that this needs to occur, so you'll have to
           manually move these files yourself.
           Support for the original dynamic sysctl node structure has
           been removed in favor of the newer layout.  This affects
           consumers of the create and delete interface, as well as
           the dynamic discovery mechanism.  This is believed only to
           be the sysctl(8) binary itself, at this point in time, so
           the only effect of this should be that a sysctl binary
           built from sources dated between 2003/12/04 and 2004/03/24
           will not work on a kernel built from sources dated after
           2004/04/25.  If you need a new sysctl binary but build.sh
           does not work, make sure that your revision of
           src/sys/sys/sysctl.h is 1.112 (or later), and then the
           do the following:
           cd /usr/src (or wherever your source tree is)
           make USETOOLS=no includes
           cd lib/libc
           make USETOOLS=no dependall install
           cd ../../sbin/sysctl
           make USETOOLS=no dependall install
           If you are using older sysctl binary, GNU autoconf would fail to
           identify your machine architecture, and tries to build binary for
           "unknown-unknown-netbsd20F" or something like that.  if that happens,
           make sure to follow the above steps.
           The ffs superblock issues listed below under 20040109 and 20030402
           are now automatically addressed by the /etc/rc.d/fixsb script or by
           sysinst when it checks a a filesystem. The manual fsck_ffs -b16 -c4
           invocation mentioned below will continue to work and is now
           automated by those scripts.  Note that under certain circumstances,
           affected filesystems upgraded to a -current kernel first before
           upgrading their userland with the fixsb and fsck_ffs fixes may
           encounter a 'freeing free inode' panic when writing to the affected
           filesystem, so it is a good idea to repair the filesystem as soon as
           possible.  For more details on the fixsb script, see pr install/25138.
           statfs(2) and friends have been replaced with statvfs(2). Before
           installing a newly build userland make sure that you are running
           a newly built kernel with COMPAT_20 set. In addition your libc
           build might not work (undefined SYS_statfs symbol) because make
           clean does not know how to remove files it does not know about
           anymore. Manually remove all generated .S sources and objects
           from the libc build directory.
           The method by which athhal-elf.o gets pulled into i386 kernel builds
           has been changed. The file is now stored as a uuencoded file in CVS
           and the generated Makefile will use the new .uue rules from bsd.file.mk
           to build it.
           This means you must have the latest bsd.files.mk installed when
           building a kernel without USETOOLS=yes.
           A bug in the cgd(4) blowfish code was corrected, without
           provision of backwards compatibility, after several public
           notices over several months. Users of cgd with blowfish cipher
           ONLY must dump their data before updating their kernels, and
           recreate cgd's and restore data using the new kernel. See
           (recent message to current-users, URL when mail-index has updated)
           On acorn32, the opms and qms drivers have been withdrawn, and
           the old wsqms driver is now called qms.  Kernel config files
           will need updating.  See the ones in sys/arch/acorn32/conf
           for examples.
           On acorn32, the beep and sysbeep devices are no longer
           needed, and will need to be deleted from kernel configuration
           Compatibility for old ffs superblock layouts has been
           added, and the restrictive fsck checks have been reenabled
           when using those layouts.  If you have been using -current
           since 20030402, you may find that fsck again signals fatal
           superblock mismatches.  To repair, make sure you have
           an updated fsck_ffs and then you can use fsck_ffs -b 16 -c 4
           to complete the filesystem upgrade.  A message has
           been added to the kernel which should detect this problem.
           See the following discussion for more information:
           New binutils builds may fail due to old dependencies.
           It's necessary to "make cleandir" to ensure that
           the dependencies will be rebuilt correctly.
           A newer mkdep is needed.  Error noting that is
                   cc: Ambiguous abbreviation --
           /usr/include/sys/disklabel_mbr.h was removed.
           It's necessary to "make cleandir" to ensure that
           the dependencies will be rebuilt correctly.
           A sign extension bug was fixed which set all the high bits
           of our newly expanded ffs fs_flags.  This should only
           affect users who installed or upgraded in September of 2003.
           A small utility program was posted to tech-kern which
           should fix this problem, and a warning message was added
           to the kernel which should discover and warn about it.  See
           With the addition of siginfo support the old signal trampoline
           code has been deprecated to COMPAT_16. Make sure that your running
           kernel has COMPAT_16 enabled before building userland.
           With the new openssl, there is some header and library shuffling.
           rm -f /usr/include/des.h /usr/include/kerberosIV/* /lib/libdes* \
           /usr/lib/libdes* before building.
           Texinfo was updated to 4.6.  To avoid failures when trying to
           build the included texinfo files, do:
           cd src/gnu/usr.bin/texinfo
           make MKINFO=no dependall install
           Groff was updated to 1.19; it's probably necessary to do
                   cd share/mk && make install
                   cd src/gnu/usr.bin/groff
                   make MKMAN=no dependall install
           Due to bugs in the export handling code, invalid export lines
           were accepted before and caused the kernel to panic when
           mountd got restarted because it freed memory that had already
           been freed. This has been fixed and the kernel checks
           export addresses very strictly. If you upgrade your kernel,
           make sure you also upgrade mountd, because if your export
           file contains lines with an old inet4 address syntax (i.e.
           a.b.c or a.b or a), they will get rejected by the new kernel.
           The superblock layout for FFS was changed.  If you have 1.6
           fsck binaries, they will signal a fatal superblock mismatch
           with the first alternate, because they compare too many
           fields (even ones that aren't useful).  If possible, upgrade
           your fsck_ffs binary before using a new kernel.
           None of this signals actual filesystem damage.
           sendmail version 8.12.8 was imported.  Since sendmail is
           now setgid to the smmsp group, and runs in "collection"
           mode for most common activities, there is a new config
           file called submit.cf that needs to live in /etc/mail.
           The generic submit.cf sample in /usr/share/sendmail/cf
           is named netbsd-msp.cf.  Upgrading your regular sendmail
           configuration file is also strongly advised.
           See the section named "MESSAGE SUBMISSION PROGRAM" in
           the updated /usr/share/sendmail/README file for more
           Texinfo was updated to 4.3.  To avoid failures when trying to
           build the included texinfo files, do:
           cd src/gnu/usr.bin/texinfo
           make MKINFO=no dependall install
           The METALOG format changed slightly, to remove the leading
           "${DESTDIR}" from path names.
           This only affects people building with UNPRIVED.
           For complete safety, remove the DESTDIR entirely and
           update tools/mtree, before running make build.
           CVS repository layout was changed.  See the following for details
           if you are using (anonymous) cvs to update your tree.
           install(1) had a '-N dbdir' option added, to specify an
           alternate location to look up users & groups (instead
           of the host system passwd(5) and group(5) databases).
           The build system was modified to take advantage of
           this option (using ${NETBSDSRCDIR}/etc), so if you
           use USETOOLS==no, you may have to rebuild and
           reinstall usr.bin/xinstall first.
           fparseln(3) moved from libutil to libc.
           If building to DESTDIR=/, reinstall the includes
           and rebuild libc:
                   make includes
                   make do-lib-libc
           If using build.sh, "cd tools/compat && make clean"
           before rebuilding the tools.
           The mk.conf(5) variable SYS_INCLUDE has been deprecated,
           including the optional "SYS_INCLUDE=symlinks" support.
           All header files, including <sys/*.h> are copied into
           The C run-time support files crtbegin.o and crtend.o
           (and their companions crtbeginS.o and crtendS.o) were
           split up, with new crti.o and crtn.o files resulting.
           This means that libtool needs to be rebuilt once the
           new libraries are installed.  The process of rebuilding
           libtool will cause it to automatically notice the new
           required files, but it *must* be rebuilt in order to
           do this.
           An out-of-date libtool will result in shared libraries
           which lack _init() and _fini() routines, which means that
           their global constructors/destructors will not be invoked.
           A bug related to how ARM ELF objects were tagged has been
           NetBSD ARM ELF uses the soft-VFP floating point model by
           default.  However, the assembler lacked support for marking
           objects as using the VFP floating point format, and the
           compiler was not properly passing the flag indicating "soft-VFP"
           to the assembler.
           Unfortunately, this means that the linker will now consider
           old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be
           incompatible with new (properly marked) objects.
           The problem will only manifest itself if you attempt to compile
           a new program using the fixed toolchain, and link that program
           against old libraries which do not have the proper "softvfp"
           The only work-around for the problem is to recompile all of
           the libraries on the system.  The easiest way to do this for
           system libraries is to install a binary snapshot; they are
           generally available on releng.NetBSD.org.  Any packages you
           have installed which supply libraries will have to be recompiled
           if you wish to link new programs against those libraries.
           If you have questions about this matter, please contact
           Systrace has been improved to support privilege elevation.
           Updating the kernel requires the userland part of systrace
           to be rebuilt.
           The config(8) grammar was changed to allow options to register
           dependencies on attributes, as well as other options.  Users
           must update and reinstall usr.sbin/config before building a new
           A new attribute dependency syntax was introduced to config(8),
           which is now used by the SCSI configuration description.  Users
           must update and reinstall usr.sbin/config before building a new
           Several changes have been made to the autoconfiguration
           framework.  Users must update and reinstall usr.sbin/config
           before building a new kernel.
           The i386mp branch has been merged.  To compile a kernel, users
           will need to add the option 'cpu* at mainbus?' to their configuration
           file.  Multiprocessor kernels will need
           ioapic*         at mainbus? apid ?
           options         MULTIPROCESSOR
           options         COM_MPLOCK
           MKDYNAMICROOT=yes enabled by default, which means that
           certain shared libraries are installed into /lib, the shared
           linker is installed into /libexec, and all programs in /bin
           and /sbin are dynamically linked.
           If you do not use "make build", you should ensure that
           you have the libraries and shared linker in the new locations,
                   make do-lib-csu do-lib-libc do-lib do-gnu-lib do-ld.elf_so
           USE_NEW_TOOLCHAIN has been replaced with:
               -   TOOLCHAIN_MISSING -- set to "yes" on platforms for which
                   there is no working in-tree toolchain (hppa, ns32k, sh5,
               -   EXTERNAL_TOOLCHAIN -- if defined by the user, points to the
                   root of an external toolchain (e.g. /usr/local/gnu).  This
                   enables the cross-build framework even for TOOLCHAIN_MISSING
           gehenna-devsw has been merged into the trunk. Need to update and
           reinstall usr.sbin/config before building the kernel.
           Crunched rescue tools (contents of /bin and /sbin, plus others)
           are now provided in /rescue.
           To ensure that these are built statically linked (no matter
           what the setting of LDSTATIC is), use a crunchgen(1) built
           from sources newer than 20020820 (see the next entry).
           crunchgen(1) changed to ensure that the generated program
           is statically linked.
           Solution: update and reinstall usr.bin/crunch
           smmsp user/group has been added for sendmail.
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           smmsp:*:17:17::0:0:Sendmail Message Submission Program:/nonexistent:/sbin/nologin
           sshd user/group has been added.  Need to hand add this in, or sshd
           will not let you log in (with default, or UsePrivilegeSeparation=yes)
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           sshd:*:16:16::0:0:& pseudo-user:/var/chroot/sshd:/sbin/nologin
           Also /var/chroot/sshd directory needs to be present (digged as part of
           the build process).
           NBUILDJOBS obsoleted in favor of just using -j.
           etc/postinstall added, which performs various checks for
           configuration file updates and changes, and can fix most of
           the problems identified.
           This should make it much easier to upgrade a system's
           configuration from earlier systems (as far back as NetBSD 1.5).
           <bsd.lib.mk> needs a new install(1) for its "-a cmd" support.
           Build and install at usr.bin/xinstall before the build.
           Raw IPv6 socket now makes strict checking for sa_family and sa_len
           on send(2) operation.  Be sure to have sbin/rtsol and usr.sbin/rtsold
           newer than November 2001 when you upgrade the kernel.
           ssh configuration files were moved from /etc to /etc/ssh.  Beware
           if you restart your machine from remote.  Note that sshd.conf needs
           to be changed (due to the use of "/etc" inside).
           Users of the VAX port will need to rebuild and install gas
           so it deal with the now present register prefix used in all
           the VAX assembly files.
           ntpd user/group has been added.  Need to hand add this in or builds
           will break as mtree aborts early.
           Add the following into /etc/group:
           and the following to /etc/master.passwd (via vipw):
           ntpd:*:15:15::0:0:Ntpd pseudo-user:/var/chroot/ntpd:/sbin/nologin
           If you're attempting to build a snapshot on sparc64 and are getting
           reloc errors from the toolchain groff binary this means your native
           toolchain has some broken C++ bits.
           To fix:
           Build a new toolchain (i.e. build.sh -t)
           Use the new toolchain to build and install natively (i.e. /usr/lib)
           After this a snapshot will be able to be built.
           In order for a sparc64 build to work you must have a working awk. If
           you've built and installed a system with the new toolchain up to this
           point you do not have a working awk as its ability to do floating
           point is broken.
           To build:
           remake and install gnu/lib/libgcc
           remake and install gnu/usr.bin/gawk into /usr/bin (make sure it links
           against the new libgcc.a)
           Kernel config information was changed to use defflag in
           the various "files" files.  Bug fixes to config(8) are
           required in order for this to work properly.  Make sure
           to build and install in usr.sbin/config before attempting
           to build a new kernel.
           libc/locale/wcstod.c now needs new lint(1). Update lint(1)
           before building libc.
           The new document BUILDING.mdoc (view with nroff | more, or
           see pre-generated .txt and .html versions) describes the build
           procedure in great detail.  BUILDING, and the USE_NEW_TOOLCHAIN
           build process, are intended in the long run to replace this
           manual update log.
           Users building a USE_NEW_TOOLCHAIN system should read the
           BUILDING document for caveats.  Generally, BUILDING supersedes
           UPDATING for these systems, as tool updating is taken care of
           by the new build system.
           src/etc/Makefile now needs install to be able to handle
           symlinks that point to nowhere. A bug in install that
           prevented this was corrected.
           Solution: update and reinstall usr.bin/xinstall
           Better Solution: Use the new toolchain and it will just work
           for you.
           /etc/mtree/NetBSD.dist has been updated to take advantage of
           absolute path support added to mtree(8). Older mtree(8)s don't
           understand the format.
           Solution: update and reinstall usr.sbin/mtree
           Crunchgen has been updated to work via reach-over makefiles. Updating
           is suggested before running a snapshot build
           The new "ubcperf" code committed by Chuck Silvers removed
           a header file, uvm/uvm_vnode.h.  There may be stale .depend
           files that still reference this file.
           Solution: "make cleandir && make dependall" in affected
           grep.info is now built from grep.texi using makeinfo.  Since it
           requires makeinfo v4.0, you need to install new texinfo before
           building gnu/usr.bin/grep.  To install new texinfo, please follow
           the instruction described in 20010726 entry.
           (i386 only): i386 kernel now uses new instructions like
           `fxsave' which old gas doesn't understand.  To build the
           kernel successfully, you need to build and install a new toolchain,
           (i.e., build.sh -t) or  (temporarily) comment out "options I686_CPU"
           from your kernel configuration until you rebuild your userland.
           See 20011029 above and BUILDING file in this directory for more information.
           [updated 20020630 since i386 gas moved when USE_NEW_TOOLCHAIN enabled]
           Bootloader update on ELF platforms.  DDB in kernels from before
           this will be unable to read symbol tables provided by newer
           Texinfo was updated to 4.0.  To avoid failures when trying to
           build the included texinfo files, do:
           cd src/gnu/usr.bin/texinfo
           make MKINFO=no dependall install
           Enabled correct .init/.fini processing in crt0.  The way this
           was done was to change a -I directive to cc(1), which means
           make(1) will have a stale dependency (it will be checking the
           timestamp on the wrong "dot_init.h").
           The symptom you will see is that new programs die with SIGSEGV
           if you have a stale dependency.
           Solution: "make cleandir" in both lib/csu and libexec/ld.elf_so
           before starting your build.
           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
                             CFLAGS and rebuilding should work)
                           usr.sbin/mdsetimage - Build a static copy if
                             building a snapshot before fully bootstrapped.
