I actually keep a full minimal install on my UFS /bootdisk slice (which 
i use geom mirror for) and then symlink /bootdisk/boot to /boot on the 
ZFS /. This way should I ever need to rollback ZFS / I can quickly 
change the vfs.root.mountfrom to /dev/mirror/gm0 and then have a base 
system living entirely on UFS. If you do it that way you can easily 
rollback your ZFS / should you need to and then just reboot back to the 
ZFS / when you're done.

Cheers,
Dillon
