I have some crushing news for you: ZFS will not be the default file system in Mac OS X Leopard. That’s as of today, June 12, 2007, at least. A senior marketing fellow for Leopard said, unequivocally, that “ZFS is not happening,” which flies in the face of what Sun said last week. Leopard is on track to use the HFS+ file system, dontcha know?

The real test will be when some do-gooder leaks the Leopard WWDC beta onto Usenet or one of those torrent sites I’ve been hearing about lately. Until then, we’re still completely in the dark.
