I'd like to start by saying "Thank you!" for your work on zfsboot :-)

Actually zfsboot is available'ish in the zfs patch (see freebsd-fs@)
Pawel made available some months ago.
I didn't try it because my old machine wouldn't boot CURRENT with a
Promise (regression). My new machine runs CURRENT just fine but from
the feedback on the zfs patch thread the patch doesn't apply to a
recent CURRENT.
I took a peek at Pawel's commits at perforce and he seems busy so
we'll just have to wait for a new patch :-)
