Nope.  OS X got a head start by syncing its userland with FreeBSD 4.x.
No UFS2 at the time.  Besides, the big reason for UFS2 was to support
extended attributes, aka "resource forks" in HFS+ speak, which Apple
already has with HFS+.

No doubt there will be plenty of cross-polination between FreeBSD 5.x
and Darwin (7.x? 8.x?).  Whether that means that UFS2 will make it into
OS X Tiger is unknown.

BTW, all praise Apple for getting Jordan Hubbard!  It'd be doubly-nice
if Apple could snag Matthew Dillon as well.  :-)
