Upgrade dari FreeBSD 6.x ke FreeBSD 7.x

This upgrades from FreeBSD 6.2-STABLE to 7.0-CURRENT.

ATTENTION: THIS UPGRADE PROCEDURE MIGHT NOT WORK FOR YOU AS YOUR ENVIRONMENT IS DIFFERENT. ALSO, THIS UPGRADE PROCEDURES MIGHT DESTROY OUR SYSTEM AND YOU POTENTIALLY MIGHT LOOSE DATA. NO WARRANTY AT ALL. SE IT AT YOUR OWN RISK!

PREPARE

• reboot once to make sure OLD system is at least
• able to still successfully reboot at all ;-)
• SORRY, THIS IS NOT A JOKE -- THIS IS A VERY SERIOUS ISSUE!

$ shutdown -r now

BUILD

• switch to a reasonable run-time environment

$ cd /; exec `/usr/bin/which bash sh | head -1`
$ PATH=/bin:/usr/bin:/sbin:/usr/sbin; umask 022; unset TMOUT

• install backward compatibility files
• (locale data to /usr/local/share/compat/, libraries to /usr/local/lib/compat/)
• notice: via binary packages as FreeBSD 7.x ports cannot be installed under FreeBSD 6.X

( cd /tmp; for pkg in localedata-5.4.tbz compat6x-i386-6.2.602110.200706.tbz; do \
 fetch -p $url/$pkg; pkg_add $pkg; rm -f $pkg; \
done )

• install latest FreeBSD Upgrade Toolkit

$ cd /usr; \
    fetch http://people.freebsd.org/~rse/dist/freebsd-adm-1.2.2.tar.gz; \
    rm -rf adm; gunzip <freebsd-adm-1.2.2.tar.gz | tar xvf -; \
    rm -f freebsd-adm-1.2.2.tar.gz

$ vi /usr/adm/cfg/csup.src
  << RELENG_6
  >> .
  (later replace "." with "RELENG_7")

• upgrade /usr/src (already required for "mergemaster -p" below!)

$ (cd /usr/src && make cleandir); \
(cd /usr/adm && make update)

• upgrade kernel configuration

$ vi /sys/`uname -m`/conf/`hostname -s | tr 'a-z' 'A-Z'`

• prepare the upgrade
• (mainly create "ftp" group)

$ mergemaster -p

• build new system

$ cd /usr/adm && make world-build kernel-build

INSTALL

• upgrade system

$ make world-install kernel-install

• cleanup system (part 1)

$ rm -f /etc/rc.d/ike /etc/rc.d/pccard /etc/rc.d/pcvt /etc/rc.d/ramdisk
  $ rm -f /etc/rc.d/ramdisk-own /etc/rc.d/usbd
  $ make etc
  $ make clean

• reboot into upgraded system

$ shutdown -r now

CLEAN UP

• switch to a reasonable run-time environment

$ cd /; exec `/usr/bin/which bash sh | head -1`
  $ PATH=/bin:/usr/bin:/sbin:/usr/sbin; umask 022; unset TMOUT

• cleanup system (part 2)

$ ( for dir in /bin /sbin /usr/bin /usr/sbin /usr/libexec /usr/libdata; do \
      find $dir -mtime +2 -type f -xdev -print; \
      find $dir -mtime +2 -type l -xdev -print; \
      done ) >/tmp/remove
  $ vi /tmp/remove
  # REVIEW FILES TO REMOVE MANUALLY
  $ cat /tmp/remove | xargs rm -f
  $ ( for dir in /lib /usr/lib; do \
      find $dir -mtime +2 -type f -xdev -print; \
      find $dir -mtime +2 -type l -xdev -print; \
      done ) | grep -v /usr/lib/compat >/tmp/move
  $ vi /tmp/move
  # REVIEW FILES TO MOVE MANUALLY
  $ for x in `cat /tmp/move`; do chflags noschg $x; mv $x /usr/lib/compat/; done
  $ cd /usr/src; make BATCH_DELETE_OLD_FILES=YES delete-old delete-old-libs

• reboot into cleaned system
• (mainly to reload the shared library cache and to
• make sure everything really still works fine)

$ shutdown -r now
