Have a look at http://lists.freebsd.org/pipermail/freebsd-current/2008-August/087391.html I have just upgraded FreeBSD-CURRENT i386 residing on external USB drive. The whole system is the classical / on UFS2 and /var, /tmp, /usr on UFS2 + SU design, only media files (music, films, photos) are on zfs. I mount zfs on demand by 'zpool import tank'. I even haven't tried to play with zfs during single user mode. After full upgrade I have done zpool import tank zpool upgrade -a zfs upgrae -a and all seems to work fine... YMMV, of course :) Just my 0.02$, Alexey.
