Leopard does / does not use ZFS, part III: it does! (kinda)

Evan Blass

Hopefully this is the last time we'll be forced to post on this topic, but we're not holding our breath: now InformationWeek -- which quoted an Apple executive this morning stating the polar opposite -- is reporting that Sun's ZFS file system IS in fact included in Leopard, albeit with a number of huge caveats. According to a company spokesperson seeking to clear up Brian Croll's "misstatement," while HFS+ continues to be the primary system used in OS X, ZFS has been coded in as a latent, "read-only option available from the command line." An IW reader claims to have accessed the system through Disk Utility's Erase menu, and states that "ZFS is only available on non-boot drives on Sun systems, so this is also the case for Leopard" -- seemingly reinforcing Croll's later assertion that Apple is really only "exploring it as a file system option for high-end storage systems with really large storage." So there you have it: Sun's Jonathan Schwartz wasn't pulling our leg after all, even if ZFS fanboys won't be pleased with the (presumably) final word on this.
