I'd like to see Apple adopt the HAMMER2 filesystem from DragonflyBSD. It's a very full-featured filesystem, with snapshots, file history, and hashes for integrity checking. Snapshots could integrate with Time Machine, and file history with Apple's file versions feature.

It doesn't have as many features as ZFS or Btrfs, but it's much better than HFS+. Plus it's BSD-licensed and unencumbered by patents, so Apple could do whatever they want with it.

That would be sweet, indeed. How far along is HAMMER2 these days?

Not far enough for Dragonfly to use it. There's a greater chance of Apple adopting BTRFS (i.e., not a snowball's chance in hell).

If they need something in the short term they could use HAMMER 1, it's been stable for years.
