stable/0.7/UPDATING

Updating Information for MidnightBSD users

20100202:
        tcsh 6.17.00

20110122:
        Import it(4) and lm(4), with support for Super I/O hardware monitors. This
        uses the sensors framework ported by Constantine A. Murenin (GSOC2007)

20110120:
        BIND 9.6.2-P3

        sudo 1.7.4-p6

20110115:
        Add experimental jme(4) for Jmicron ethernet devices.

20101130:
        A double free exists in the SSL client ECDH handling code, when
        processing specially crafted public keys with invalid prime
        numbers. [CVE-2010-2939]

20101120:
        Several portions of the kernel and userland code related to UFS file 
        systems (and UFS2) cannot properly handle inode counts above 2^31 due
        to use of int types.  Based on a patch from FreeBSD, I've modified
        our UFS2 implementation to handle unsigned values for inode counts
        which should allow for file systems greater than 16TB.

        newfs and growfs was also modified.

20101110:
        Fix a security issue with pseudofs which could result in running code in kernel
        context or a kernel panic depending on system configuration.  This affects file
        systems such as procfs for instance.

20101021:
        sysrc is a utility to print and modify name/value pairs in /etc/rc.conf easily.
        This is similar to functions present in many linux distros. The utility was
        written by Devin Teske for FreeBSD.

20100920:
        bzip2 security patch for integer overflow.

20100905:
        MidnightBSD RELENG_0_3 branch created.  Aggressive development continues here
        for 0.4.

20100902:
        Fix a security issue with libutil that allows users to bypass cpu limits in
        login.conf in some cases.  This combined with OpenSSH for example can allow
        the user to get more resources than they're allowed.

20100822:
        Import Apple's mDNSResponder (mdnsd).

20100814:
        libdispatch added to MidnightBSD.  This provides functionality found in
        Mac OS X's GCD.  We do not have blocks support yet.  As this code is
        licensed under Apache 2, we create a new MK_APACHE option so that
        it's not required for all users to run code under a license they
        may not like.

20100713:
        mbuf readonly fix related to sendfile(2) data corruption.

20100704:
        brainfuck(1) imported from MirBSD.

20100505:
        zlib 1.2.5

20100430:
        Sudo 1.7.2p6 imported

20100321:
        Update zlib to 1.2.4

20100319:
        Removed i586 from default i386 generic kernel.

20100317:
        Update to tzdata2010e (time zones).  This includes changes in
        Mexico.

        Add support for several newer sound cards via hda including
        ATI and Realtek chipsets.

20100313:
        CPU detection has been changed.  VIA Padlock detection added.

20100312:
        Fix a number of bugs and compiler warnings in libmport. Handle
        plus signs in paths for mport.check-fake

20100311:
        mksh R39c

20100309:
        Sudo 1.7.2p5

        sqlite3 3.6.23

        mksh R39b

        libffi (ffi) 3.0.9

20100206:
        WITHOUT_LIB32 is no longer needed on AMD64.  GCC was fixed to
        properly pass arguments to ld.

        re(4) and rl(4) have been updated to support several new
        realtek chipsets.  Performance has been improved on re(4).

20100204:
        Fix a bug cropping up on AMD64 MidnightBSD with sftp
        segfaulting.  

20100116:
        Import ash changes from FreeBSD (bin/sh) 8-Stable.

        BIND 9.6.1-P2

20100110:
        Import Sendmail 8.14.4. Fix for SSL vulnerability.

        posix_spawn(3) added to MidnightBSD libc.  Users may need to build and
        install libc before doing a full buildworld when upating from 0.2 or
        older current systems.

        kqueue(2) was modified to support portions of libdispatch functionality.

20100106:
        Bind security update.  Fix a bug with DNSSEC that causes negative
        cache entries and thus a possible DNS cache poisoning attack.

        Fix a bug in ZFS that can reset permissions on system crashes.

20091228:
        amdtemp(4) was added.  It allows one to monitor to the temperature
        of an AMD CPU such as a Phenom.

20091205:
        OpenSSL security fix

        The SSL version 3 and TLS protocols support session renegotiation without
        cryptographically tying the new session parameters to the old parameters.

20091128:
        OpenBSD sensors framework imported including sensorsd(8)

20091126:
        OpenNTPD 4.4 import

        Update OpenSSH to 5.3p1

        mksh R39

20091124:
        cpdup updated from DragonFly to 1.15

        tzdata2009s updated with latest timezone data for November 2009.

20091010:
        amd64 users should use WITHOUT_LIB32=yes in /etc/make.conf for now
        to test current.

        Revert unicode filename fixes from ntfs code.  This was causing chaos
        on amd64 systems.

20091006:
        Update timezone data with tzdata2009n with the Pakistan and
        Argentina changes.

        Sync several userland utilities with versions from FreeBSD 7.0 in
        sbin and usr.sbin.

20090919:
        Update timezone data with tzdate2009m from September 2009.

20090729:
        Patch for Bind 9 security vulnerability. a dynmaic update packet 
        can trigger an assertion and cause named to exit

20090606:
        Remove PCC from the base system.  This compiler will not work
        as a system compiler for us as we've got some userland investment
        in C++ code and may have Objective-C in the future.  We're stuck
        with a solution that supports these three languages at a minimum.

        I had wanted to keep it as an optional compiler because it is
        fast, however too many users want to try to use it for the base
        system which makes no sense.

        A hack was added for Cypress based usb hard drive enclosures to
        the kernel.  This should cut down on commands it claims to support
        but does not (at the cam layer).  Found while testing ZFS on
        an external device.

20090520:
        The powerd daemon no longer starts automatically to improve
        compatibility with many systems.  However, there is a new
        installer option in the startup section to enable it. This
        makes it easier to enable for users that have working systems. I                thought it was only a problem on older hardware, but it freaks
        out my new Phenom too.

20090502:
        OpenSSH 5.2p1 import

        ale(4) connected to the build. (kernel module only)

20090501:
        Imported makefs utility from NetBSD/FreeBSD

20090422:
        OpenSSL security update

        The function ASN1_STRING_print_ex does not properly validate the lengths
of BMPString or UniversalString objects before attempting to print them.

20090415:
        Created a Symbol.map for libc/ohash symbols

        Updated several usr/bin usr/sbin utilities.

        Corrected a bug with Makefile.inc1 causing the bootstrap
        tools to fail.

20090405:
        xorg 7.4 wants to configure its input devices via hald which does not
        yet work with USB. If the keyboard/mouse does not work in xorg then
        add
                Option "AllowEmptyInput" "off"
        to your ServerLayout section.  This will cause X to use the configured
        kbd and mouse sections from your xorg.conf

20090403:
        mksh was disconnected a few day ago do to bugs with
        buildworld and mports.  Now, connect it back 
        for use as /bin/sh with a conditional called
        MK_ASH.  By default, ash is the standard /bin/sh
        but we may change this later.  This will allow further
        testing by users and developers of mksh without
        causing an unpleasant default experience.  In the
        long run, we need to fix mksh compatibility.

20090328:
        Bring in mksh R37 from CVS. The dot.mkshrc files for root 
        and skel were changed.  mksh(1) now replaces ash aka sh(1)
        as the default /bin/sh.  Please report bugs with
        ports, etc. The ash code will remain in the repo for awhile
        as I decide if we'll add something like MK_SHELL_ASH as
        an optional build parameter.  

        ahd was disconnected from the lint environment until
        the compiler bug is sorted (by updating gcc?)

        Remove freebsd-tips from fortune files and change the
        default for login and profile.

20090327:
        Update libarchive to 2.5.5, tar, and add bsdcpio.

        Also previously, ctriv has been connecting Perl 5.10
        to the build (part of os).  This will have an impact
        on mports.

20090325:
        Update Bind to 9.4.3-P1

        Update mksh to R36b

        Update tcpdump to 3.9.8, fix libpcap to work with current.

        Update pnpinfo, sync with FreeBSD.

20090115:
        Fix a problem with DNSSEC and BIND.

20090110:
        For applications using OpenSSL for SSL connections, an invalid SSL
        certificate may be interpreted as valid.  This could for example be
        used by an attacker to perform a man-in-the-middle attack.

        Other applications which use the OpenSSL EVP API may similarly be
        affected.

        Stop cross site request forgery attacks in lukemftpd

20090104:
        Import GNU libreadline 5.2

20090101:
        Update time zone data to 2008i.

20081231:
        Correct a problem where bluetooth and netgraph sockets are not
        properly initialized.

        Happy 2009.

20081206:
        Due to the massive change in the underlying system under way,
        we're naming the next release 1.0.  The sys/sys/param.h was
        changed accordingly.  ipfilter and ncurses were corrected
        using __MidnightBSD__ tests in the code.  

        The GENERIC kernel config was caught up on i386 today.  Consider
        i386 still broken, but amd64 is running again. 

        mdoc.local was updated with the new MidnightBSD version info.

        batt(1) was rewritten in C.  It now supports several flags and
        runs about 8 times faster on my laptop.  The default output
        shows the number of minutes of battery life remaining and the
        percentage.  You can use -u to display the number of batteries or
        -c to get script friendly output.  Consult the man page for more.

20081204:
        Work has completed on importing ZFS, jemalloc, several
        new devices, SCTP, updated pf, a new tempfs, linuxolator 2.6 kernel
        support, improved locking for file desc., audit (openbsm), 
        openssl .98e, nfe, imporved intel high def audio, midi, updated
        intel gigabit (em), support for several wifi cards (intel), ...

        Renamed 0.3-CURRENT officially. Switched to using MidnightBSD version
        data from param.h instead of the FreeBSD version.  This means
        testing is now possible in the ports tree for the version
        and that any ports or code relying on the FreeBSD version from
        sys/sys/param.h will need to be fixed.

20080905:
        update nve(4) to support new hardware.

20080801:
        Import OpenBSM 1.0

        Modify src/release to create 3 isos instead of 2 for packages.

        etc/rc.d/firstboot now enables kdm, gnustep + slim and bsdstats.

        Many ia64, alpha, powerpc items were removed. 

        The recent diffutils 2.8.7 import was fixed.

20080703:
        pcc was not installed properly when setting DESTDIR for live cds, 
        or posibly jails. 

20080627:
        Add firmware(9), WEP, CCMP, TKIP to GENERIC.

        Add glabel to GENERIC.

        Intel ICH8 mobile chipset used on some iMacs included with ata.

        pcc connected to the build on i386. (alternative compiler)

        ath added to GENERIC.  (Atheros wireless NICs) on amd64/i386

20080528:
        Sendmail 8.14.3

20080516:
        ssh-vulnkey allows you to look for vulnerable ssh keys that
        were generated on Debian and Ubuntu hosts over the last
        few years.  sshd can block offending keys with a configuration
        option.

        The elf note on binaries is now set to MidnightBSD.

20080514:
        Fixed a number of problems with pcc.  It is not yet connected
        to the build, but usable on i386 hosts.  You may use it 
        by make; make install in /usr/src/usr.bin/pcc.  It will
        install in /usr/local as some of the files conflict with
        GCC versions. __MidnightBSD__ is defined in PCC as well.

        System headers were fixed to allow pcc to compile many binaries
        on MidnightBSD.  bin/cp will work now for instance.

20080430:
        __MidnightBSD__ is now defined via gcc.  This can be tested
        to determine we're running on MidnightBSD in the preprocessor.

20080429:
        Import bind 9.4.2 with threading

        libpthread (KSE) and libthr are built earlier
        
        pcvt(4) removed!

        Alias added for core2 cpus.

        Alpha and PC98 only utilities removed from usr/sbin

        syslogd, adduser, rmuser, mergemaster and mailwrapper have been
        improved.  See the man pages for info.

        periodic scripts will not send emails with empty message bodies.
        See mailwrapper fix.

20080410:
        Sync cpdup with DragonFly.  Add parallel transaction support and
        -l flag to line-buffer stdout and stderr.

20080406:
        Import bzip2 1.05
        Import OpenSSH 4.9p1

20080322:
        The default umask was changed to 022.
        
        /usr/X11R6 paths were removed from several config files.

        .mkshrc files are now installed for root.

20080316:
        FIx a problem with gif0 tunnels and neighbors with IPV6.

20080312:
        Add lndir from X.org.  This aides in the porting of MirPorts.

        New OS versions were added to the mapage code (groff)

20080310:
        Correct a buffer overflow in ppp.

20080308:
        Remove /usr/X11R6 from manpath config.

20080307:
        Atheros driver no longer has several options set
        which corrects building in tinderbox on all three platforms.

        Added a new macro to sx.h which returns true if the current
        thread holds an exclusive lock on a specifix sx.

        Removed OS/2's HPFS file system.   It's not maintained and
        I don't know anyone using OS/2 or ecomstation these days.
        My copy is in the closet collecting dust.

20080306:
        Synced tinderbox with FreeBSD.  Modified it for MidnightBSD.
        Developers can now use it to check src builds.

20080303:
        Add mksh to /etc/shells, made some adjustments to options
        for mksh builds per suggestion upstream.

        USB HID table updated with modern hardware list.

        Updated BSD family true (we're not in there yet)

        iso3166 file updated and import of tzdata2007k for 
        new time zones.

        Updated mksh to latest version R33.

20080228:
        Remplaced the random IP id generation code with a new
        version by Amit Klein.

20080221:
        Sendfile write only permissions fix.

        Removed some HPFS and PC98 code.

        iso639 file sycned with DragonFly.

20080128:
        Changed NTP configuration so that ips aren't cached
        so multiple servers are used.

        Fix an issue with fork() in libpthread.

20080121:
        Add virtualization detection to set the HZ rate
        according to a VM present.  VMWare and Parallels
        should work better like this.

        Change to full x11 install in sysinstall.  Add
        xorg 7 support.

20080115:
        Fix the handling of PTY's.  CVE-2008-0216

20080105:
        mport delete code added, USE_MPORT_TOOLS knob aded.

20080101:
        Happy New Year

20071123:
        Update sendmail to 8.14.2

20071120:
        Update system compiler to gcc 3.4.6.

20071023:
        Updated mksh to R31d.

20070911:
        Updated mksh to version R31b.

        Fixed stderr output in libpthread.  Previously it was
        written to stdout.

20070831:
        Added dot.mkshrc file to support the recent change to 
        mksh from OpenBSD's ksh derived from pdksh.  

        Added new firewall configuration.  ipfw is enabled by default
        with a "desktop" configuration.  Consult /etc/rc.firewall
        or ipfw show to see the ruleset used.  You can disable
        ipfw by setting firewall_enable="NO" in /etc/rc.conf This
        change only effects IPv4.  IPv6 does not have a firewall
        enabled by default.

20070814:
        Removed GNU tar source.  We've been using BSD tar 
        for awhile.

20070806:
        Finished removing umapfs and autofs from the tree.

20070804:
        BIND and Tcpdump have been patched for recent vulnerabilities.

        We switched to BSD cpio (pax).

20070719:
        Imported cpdup from DragonFly as /bin/cpdup

20070716:
        Update GNU cpio to 2.8. 

20070410:
        cvs was updated to 1.12.13.  cvsbug was removed.
        cvs now behaves similarly to DragonFly's cvs with
        most of their local changes.  

20070409:
        RELENG_0_1 was created. More aggresive changes will
        continue here.

20070406:
        Back out propolice.  propolice caused several problems
        with our threading libraries libthr and libpthread.  
        curthread was often NULL after the patch and many
        multithreaded applications would crash.  We plan to 
        work on either bringing in gcc 4.1 or developing a new
        patch which also corrects our threading issues later.

        It is more important to have a stable system for our
        mport work and other projects at this time.

        This is not a clean removal.  It is recommended that you
        have a recently SNAP CD handy.  You can either reinstall
        or perform a make buildworld and make buildkernel and 
        make installkernel.  Reboot on the cd and copy the contents
        of /bin, /sbin, /lib, /libexec, and /usr/bin, /usr/sbin,
        /usr/lib, and /usr/libexec to the respective directories on
        your disk.  Then you should be able to boot into single user
        mode and run make installworld.  You will need to run
        chflags noschg on some of the files if you can't overwrite
        them. 

        You will get __guard missing errors since we had to remove
        this from libc.

        You will need to rebuild any ports built while propolice was
        installed.

20070401:
        Importing propolice into MidnightBSD. Propolice is going to
        provide us with much greater security and stability in the
        long run. If upgrading from a pre-propolice system, please
        follow the these instructions:

        cd /usr/src/lib/libc && make obj && make && make install
        cd /usr/src/gnu/usr.bin/cc && make obj && make && make install
        cd /usr/src/lib/libpthread && make obj && make && make install
        cd /usr/src/lib/libthr && make obj && make && make install
        buildworld and kernel

        It is adviced that any mports which were installed and/or built
        prior to the propolice update also be updated. If any errors
        or issue are encounted, please contact security@midnightbsd.org
        and we will be sure to investigate and come up with an expeditious
        fix.

20070314:
        Remove send-pr from src.

        Switch to NetBSD's gzip.

        Bump MBSD minor revision.

20070313:
        Imported OpenSSH 4.6p1.

        Imported FreeBSD's libarchive and updated tar to work with it.

        Disabled debug statements cluttering up /var/log/messages for
        the tcp autobuf patch applied previously.

20070312:
        Synced several audio changes from FreeBSD 6.1. Removed the 
        BSD Daemon files from src/share.  

20070308:
        Added mfi which supports LSI Logic MegaRAID SAS devices including
        the Dell perc5i.

20070206:
        Imported OpenBSD's sudo into source. Please install
        /usr/src/usr.bin/sudo/lib first before building.

        Those who install from a snapshot after this date
        will not be effected.

20070119:
        Added audit group.  Be sure to add audit to your /etc/group file
        before installing world.

        hostapd was updated to 0.4.8.

        An accidental commit in usr.sbin/bluetooth/hccontrol was fixed to
        unbreak world.

        wpa_supplicant was updated.

        For stability and compatibility reasons, it was decided that MidnightBSD
        sync with FreeBSD 6.1 Release.  Nearly every change between the original
        fork date of February 24, 2006 and the release of FreeBSD 6.1 in May
        2006 will be merged.  Beyond this, MidnightBSD will be a "real" fork and
        will not sync every little change with FreeBSD.

20061231:
        Updated COPYRIGHT for 2007.

        Updated and bumped libutil after importing NetBSD efun(3) functions.

        Added MidnightBSD_version and bumped the FreeBSD version as we've
        synced all commits between the fork and that version.  It is now safe
        to assume MidnightBSD is compatible with FreeBSD RELENG_6 from
        Feb 26, 2006.

        Added spell(1) and deroff(1) from NetBSD.  Also added additional
        dict files to work with it. /usr/share/dict/american, 
        /usr/share/dict/british and /usr/share/dict/special/math

        Numerous man page and bug fixes.

20061226:
        Setup /usr/share/examples/cvsup SUPfiles for the new
        MidnightBSD CVSup server. 

        Fix a bug in burncd where it would continue forever while
        erasing CDRW media.

        Add csup to /usr/bin.  csup is a CVSup replacement written
        in C. 

        Fixed a bug with bsnmpd build from Oct 30.  

        Corrected some race conditions and fixed a few bugs in
        geom.  Imported changes from FreeBSD RELENG_6.

20061225:
        Fixed a typo in src/lib/libc/sparc64/fpu/fpu_implode.c
        that caused long double to long and long long 
        conversion of negative numbers to always result in -1.

20061221:
        Fixed acpi_battery.c to not report an ERROR if no
        batteries are present.

        Performed some minor updates on the RL and RE NIC drivers.
        RL should no longer panic when trying to print errors.

        Corrected a bug with TTY.

20061218:
        Corrected a bug with libpthread where newly created suspended
        threads don't get scheduled.

20061206:
        Fixed a typo with the firewire security patch.

20061129:
        Minor cleanups to utilities in bin.

        Fixed msdos file system short file name behavior to match
        FreeBSD.

20061031:
        Updated man pages in section 7.

20061030:
        Updated sys/dev/drm to support intel 915 and radeon 
        r300 cards properly.  

        Synced snmpd with FreeBSD-stable.

        Fixed a bug in rm which could cause data loss.  

20061027:
        Added Intel ICH8 and nForce 5 support to ATA. cam, mpt,
        random, kbdmux, atkbd, and usb were updated.  Changes
        to clearing registers on SSE enabled processors (i386)
        commited.  

        lukemftpd updated.  

        openssh rc script was altered which effects initial
        seeding.  

20061014:
        Workaround for em driver problem on shared IRQ.

        Started removal of alpha support.

20061013:
        ATA driver was updated.  USB/USB1/USB2 types added.

20061010: 
        OpenSSH was updated to 4.4p1.   

20060909:
        OpenNTPD was added to MidnightBSD.  Run make delete-old to remove
        the old ntpd daemon.

        cat has a new option -D which allows you to timestamp output
        on a per line basis.

        The kernel has a keyboard mux which allows you to have multiple
        keyboard connected simultaneously.  USB keyboard support was also
        improved with this patch.

        The Intel em driver was updated.  Network performance was greatly
        increased on many systems.  Additional models are supported.

        The ATA driver was patched to fix a potential deadlock.

        Bind was patched to fix a potential denial of service condition.

20060817:
        ksh has been added to the base system.  If you previously had
        the port installed, it will be overwritten on the next buildworld.


        To build a kernel
        -----------------
        If you are updating from a prior version of MidnightBSD (even one just
        a few days old), you should follow this procedure. With a
        /usr/obj tree with a fresh buildworld,
        make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE
        make -DALWAYS_CHECK_MAKE installkernel KERNCONF=YOUR_KERNEL_HERE

        To test a kernel once
        ---------------------
        If you just want to boot a kernel once (because you are not sure
        if it works, or if you want to boot a known bad kernel to provide
        debugging information) run
        make installkernel KERNCONF=YOUR_KERNEL_HERE KODIR=/boot/testkernel
        nextboot -k testkernel

        To just build a kernel when you know that it won't mess you up
        --------------------------------------------------------------
        This assumes you are already running a 6.X system.  Replace
        ${arch} with the architecture of your machine (e.g. "i386",
        "amd64", "ia64", "pc98", "sparc64", etc).

        cd src/sys/${arch}/conf
        config KERNEL_NAME_HERE
        cd ../compile/KERNEL_NAME_HERE
        make depend
        make
        make install

        If this fails, go to the "To build a kernel" section.

        To rebuild everything and install it on the current system.
        -----------------------------------------------------------
        # Note: sometimes if you are running current you gotta do more than
        # is listed here if you are upgrading from a really old current.

        <make sure you have good level 0 dumps>
        make buildworld
        make kernel KERNCONF=YOUR_KERNEL_HERE
                                                        [1]
        <reboot in single user>                         [3]
        mergemaster -p                                  [5]
        make installworld
        make delete-old
        mergemaster                                     [4]
        <reboot>


        To cross-install current onto a separate partition
        --------------------------------------------------
        # In this approach we use a separate partition to hold
        # current's root, 'usr', and 'var' directories.   A partition
        # holding "/", "/usr" and "/var" should be about 2GB in
        # size.

        <make sure you have good level 0 dumps>
        <boot into -stable>
        make buildworld
        make buildkernel KERNCONF=YOUR_KERNEL_HERE
        <maybe newfs current's root partition>
        <mount current's root partition on directory ${CURRENT_ROOT}>
        make installworld DESTDIR=${CURRENT_ROOT}
        cd src/etc; make distribution DESTDIR=${CURRENT_ROOT} # if newfs'd
        make installkernel KERNCONF=YOUR_KERNEL_HERE DESTDIR=${CURRENT_ROOT}
        cp /etc/fstab ${CURRENT_ROOT}/etc/fstab                    # if newfs'd
        <edit ${CURRENT_ROOT}/etc/fstab to mount "/" from the correct partition>
        <reboot into current>
        <do a "native" rebuild/install as described in the previous section>
        <maybe install compatibility libraries from src/lib/compat>
        <reboot>


        To upgrade in-place from 5.x-stable or higher to 6.x-stable
        -----------------------------------------------------------
        <make sure you have good level 0 dumps>
        make buildworld                                 [9]
        make kernel KERNCONF=YOUR_KERNEL_HERE           [8]
                                                        [1]
        <reboot in single user>                         [3]
        mergemaster -p                                  [5]
        make installworld
        make delete-old
        mergemaster -i                                  [4]
        <reboot>

        Make sure that you've read the UPDATING file to understand the
        tweaks to various things you need.  At this point in the life
        cycle of current, things change often and you are on your own
        to cope.  The defaults can also change, so please read ALL of
        the UPDATING entries.

        Also, if you are tracking -current, you must be subscribed to
        freebsd-current@freebsd.org.  Make sure that before you update
        your sources that you have read and understood all the recent
        messages there.  If in doubt, please track -stable which has
        much fewer pitfalls.

        [1] If you have third party modules, such as vmware, you
        should disable them at this point so they don't crash your
        system on reboot.

        [3] From the bootblocks, boot -s, and then do
                fsck -p
                mount -u /
                mount -a
                cd src
                adjkerntz -i            # if CMOS is wall time
        Also, when doing a major release upgrade, it is required that
        you boot into single user mode to do the installworld.

        [4] Note: This step is non-optional.  Failure to do this step
        can result in a significant reduction in the functionality of the
        system.  Attempting to do it by hand is not recommended and those
        that pursue this avenue should read this file carefully, as well
        as the archives of freebsd-current and freebsd-hackers mailing lists
        for potential gotchas.

        [5] Usually this step is a noop.  However, from time to time
        you may need to do this if you get unknown user in the following
        step.  It never hurts to do it all the time.

        [8] In order to have a kernel that can run the 5.x binaries
        needed to do an installworld, you must include the COMPAT_FREEBSD5
        option in your kernel.  Failure to do so may leave you with a system
        that is hard to boot to recover. A similar kernel option COMPAT_FREEBSD5
        is required to run the 5.x binaries on more recent kernels.

        Make sure that you merge any new devices from GENERIC since the
        last time you updated your kernel config file.

        [9] When checking out sources, you must include the -P flag to have
        cvs prune empty directories.

        If CPUTYPE is defined in your /etc/make.conf, make sure to use the
        "?=" instead of the "=" assignment operator, so that buildworld can
        override the CPUTYPE if it needs to.

        MAKEOBJDIRPREFIX must be defined in an environment variable, and
        not on the command line, or in /etc/make.conf.  buildworld will
        warn if it is improperly defined.
