FreeBSD 6.0 to 6.1 binary upgrade

Using this script, I just upgraded the FreeBSD Portsnap buildbox to FreeBSD 6.1. The following is a transcript of the upgrade process (generated using script(1)), with a few spaces added to help web browsers wrap the text:

The following files from FreeBSD 6.0 have been modified since they were
installed, but will be deleted or overwritten by new versions:
/usr/share/examples/etc/group /usr/share/man/whatis

The following files from FreeBSD 6.0 have been modified since they were
installed, and will not be touched:
/etc/crontab /etc/hosts /etc/mail/aliases /etc/manpath.config
/etc/master.passwd /etc/motd /etc/passwd /etc/pwd.db /etc/shells
/etc/spwd.db /var/db/locate.database /var/log/sendmail.st

The following files from FreeBSD 6.0 have been modified since they were
installed, and the changes in FreeBSD 6.1 will be merged into the
existing files:
/etc/group

Not shown above is the shutdown -r now needed to reboot into the newly upgraded FreeBSD 6.1 system, of course. Including the reboot, this upgrade took under 11 minutes, and for most of that time it was running unattended while I read slashdot -- not bad for picking up 6 months worth of bug fixes and performance improvements.

RIP FreeBSD 4.10 (May 27, 2004 -- May 31, 2006)

This means that a lot of people should be upgrading to new releases soon. I've published some instructions in the past for performing such upgrades using the released ISO images, but even these simplified instructions aren't foolproof. As part of the work I'm doing right now on FreeBSD Update I expect to put together a much simpler release-to-release upgrade script.

Watch this space!
