This Apple Does Fall Far From The B-Tree

That old adage: the apple doesn't fall far from the tree, doesn't apply to Apple the corporation. According to ArsTechnica today, Apple abruptly abandoned its open-source project to port Sun's ZFS as the filesystem for Mac OS X, on October 23rd.

The speculation is that Sun licensing fees may have been viewed as a roadblock to adoption or possibly there are growing concerns that Oracle's acquisition of Sun could cause other problems. In the meantime, Apple is hiring engineers to build its own advanced filesystem, instead of adopting either ZFS or its Linux derivative BtrFS.
