Well, part of the idea behind ZFS is that these parts are _not_ separated in "layers" -- for instance, the filesystem can push data down to the RAID level to determine the stripe size used. Whether this is a good idea is of course hotly debated, but I don't think you can port just the filesystem part and call it a day. /* Steinar */ -- Homepage: http://www.sesse.net/
