The OP says he does have an external drive which the bios does not allow
He can he back up (tar) the current system that is UFS based to the
clobber the ufs partition by simply formatting it as a ZFS partition,
and at some
point, (after appropriate admin of zfs partition), tar the system back
into the zfs partition.
Is this "doable"? (Pardon the bad "english").
