Roskolnikov writes "Apple has apparently decided that ZFS isn't really ready for prime time. We've been discussing Apple/ZFS rumors, denials, and sightings for some years now. Currently a search on Apple's site for ZFS yields only two hits, one of them probably an oversight in the ZFS-cleansing program and the other a reference to open source. Contrast this with an item from the Google cache regarding ZFS and Snow Leopard. Apple has done this kind of disappearing act in the past, but I was really hoping that this was one feature promise they would keep. I certainly hope this isn't the first foot in the grave for ZFS on OS X."
