FreeBSD UpdateThe freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.0-RELEASE, 7.1-RELEASE, 7.2-BETA, 7.2-RC1, or 7.2-RC2 can upgrade as follows:
# freebsd-update upgrade -r 7.2-RELEASEDuring this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly.
# freebsd-update installThe system must be rebooted with the newly installed kernel before continuing.
# shutdown -r nowAfter rebooting, freebsd-update needs to be run again to install the new userland components, and the system needs to be rebooted again:
# freebsd-update install # shutdown -r nowUsers of earlier FreeBSD releases (FreeBSD 6.x) can also use freebsd-update to upgrade to FreeBSD 7.2, but will be prompted to rebuild all third-party applications (e.g., anything installed from the ports tree) after the second invocation of “freebsd-update install”, in order to handle differences in the system libraries between FreeBSD 6.x and FreeBSD 7.x.

この後、Updateで削除されるファイル、追加されるファイル、更新されるファイルの一覧が表示されて終了。
% sudo du -hs /home/tmp/freebsd-update

と、それなりのサイズに。
次のコマンドで、実際にインストールされる。
% sudo freebsd-update install -d /home/tmp/freebsd-update
Installing updates…
Kernel updates have been installed. Please reboot and run
“/usr/sbin/freebsd-update install” again to finish installing updates.
% sudo shutdown -r now
を叩いた後、１分ほど黙祷。その後、sshでログインしてみる。
ログインできたら、メッセージの通り再度、
% sudo freebsd-update install -d /home/tmp/freebsd-update
Installing updates… done. ← そこそこ時間掛かる
でUpgrade完了。
% uname -r
7.2-RELEASE
ついでに、7.2-RELEASEが更新されたら通知してくれるよう、cronの設定もしておく。
% sudo vi /etc/crontab
0 3 * * * root /usr/sbin/freebsd-update cron -d /home/tmp/freebsd-update
を最終行に追加。
freebsd-update cron は、基本fetchと同じらしい。違いは、処理開始前に、1 ～ 3,600秒スリープすることと、結果をメールすることくらい。
man freebsd-update
に書いてある。
view /usr/sbin/freebsd-update
で、ソース見た方が早いかも。かなり見易く綺麗なソースだ。
