FreeBSD can often be booted from USB, it'll look as if you're booting from a scsi disk. "Often" because people have trouble booting supermicro server motherboards (with xeon woodcrest, e.g.) - something doesn't work in boot code, it doesn't get to the boot loader or kernel. Maybe grub will help with that... I have both 6.2 and 7-current booting and running off the read-only usb flash drives (128MB is enough for having bgp by quagga and a ton of not-that-much needed packages, like rrdtool, midnight commander, perl-5.8... thanks to geom_uzip, 256MB allows having all ofthe compiler stuff and even more packages). You'll have to modify startup scripts for things I'm also running 7-current with ZFS (/usr is ZFS, and anything but root and /var is ZFS) ever since it appeared in the source tree. There are stability issues if you go after heavy i/o, they may not be related only to ZFS. You can expand zfs pool - zpool add -f bla-bla Don't do that :). Without -f it'll not work for raidz. Seems the problem in expanding of raidz array is somewhat math-related - as the information on all of the device depends on every other device - so it's not straightforward how to expand it.
