What I did is the following: 2GB CF card + CF to ATA adapter (today, I would use 2x8GB USB sticks, CF2ATA adapters suck, but then again, which Mobo has internal USB ports?) Filesystem 1024-blocks Used Avail Capacity Mounted on /dev/ad0a 507630 139740 327280 30% / /dev/ad0d 1453102 1292296 44558 97% /usr /dev/md0 253678 16 233368 0% /tmp /usr is quite crowded, but I just need to clean up some ports again. /var, /usr/src, /home, /usr/obj, /usr/ports are all on the GELI+ZFS pool. If /usr turns out to be to small, I can also move /usr/local there. That way booting and single user involves trusty old UFS only. I also do regular dumps from the UFS filesystems to the ZFS tank, but there's really no sacred data under / or /usr that I would miss if the system crashed (all configuration changes are tracked using mercurial). Anyway, my point is to use the full disks for GELI+ZFS whenever possible. This makes it more easy to replace faulty disks or grow ZFS pools. The FreeBSD base system, I would put somewhere else.
