But you can always test it out. I'm using zfsboot on my note PC, and not using UFS. I know many problems about it:-). 1. zpool configuration is too limited, only single and mirror usable. If you want to zfsboot, you can't use RAIDZ, striping and cache(zpool add ... cache ...):-(. 2. On some environment (old BIOS?), zfsboot1 can't chain to zfsboot2. Because, by size (512bytes), zfsboot1 didn't support CHS mode. 3. Yes, a bit undocumented. So you must be careful. 4. I tried to test about zfsboot supported liveCD, but I can't make it yet. Because zfsbootable loader can't boot from CD. SEE ALSO: http://lists.freebsd.org/pipermail/freebsd-fs/2008-July/004895.html http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/125878
