It depends. If no changes are needed to the FreeBSD kernel API/ABI that will make it impossible to merge to 8.x, chances are new ZFS will appear in 8.x as well. Of course if 8.x will still be around:) --=20 Pawel Jakub Dawidek http://www.wheelsystems.com pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
