On February 28th FreeBSD 7.0 was finally released, and one of the many new features is Experimental support for Suns ZFS file system!
Last year at EuroBSDCon (the annual European BSD conference), the FreeBSD developer Pawel Jakub Dawidek accounted for the process of porting ZFS to FreeBSD. What really surprised him, was that it had only taken about 10 days to port the core functionality of ZFS to FreeBSD, because the code was so modular and well documented. Of course there was quircks, but it worked.
Pawel also took his own presentation a step further and showed a video of the superhero ZFS-Man:
At MacOSForge they are also working hard, to get the full implementation of ZFS into Apples OS X 10.5 - Leopard, so its not stuck at read-only access. Their ZFS implementation is now in sync with Solaris build 72.
Its good to see ZFS being embraced into the open source community
