The hacks sounds good until 8.2 is released however, regarding this upgrade,

with the newer versions of the utilities?
No -- the on-disk format is different. ZFS will run fine with the older
on-disk formats, but you won't get the full benefits without updating
them. You'll need to run both 'zpool update -a' and 'zfs update -a' --
this is a non-reversible step, so be certain you will never need to
downgrade before doing it. Also, you *will* need to update gptzfsboot
on your drives, or you will come to a sticky end if you try and reboot.
Something like this:
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad0
Cheers,
Matthew
This part applies only if you're booting from ZFS drives?
