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 :-) -- Joao Barros
