Apple just confirmed to InformationWeek that there will be NO ZFS in Mac OS.

Quote:

Senior director of product marketing for the Mac OS Brian Croll told IW point blank that "ZFS is not happening,"


I am speculating here, but with reason... It could be that plans were well under way to feature ZFS in the release version, even as the default filesystem, but because of Sun's arrogance and pre-announcement, Apple pulled the feature. It wouldn't be the first time.

Some years back ATI slipped and pre-announced (by a couple of days) RADEON on Mac before Apple unveiled their new machines. Steve Jobs was supposed to bring ATI's CEO on stage for that keynote and do a whole segment on the RADEON. Instead there was no mention of the graphics and RADEON was pulled from the first revisions of that desktop.

We could be seeing the same thing again.
