Pitty
That is a pitty. ZFS is a revolution in the filesystem world. It should be a piece of cake for a company such as Apple to integrate it in the OS. I don't understand why Apple and Microsoft bother to build their own filesystem. That is not their core business. They should rather focus on the user experience. In the meantime people have to live with crap filesystems such as HFS+ and NTFS. I have had to reinstall both Mac OS X and Windows several times, just because it is possible their filesystems can get corrupted. Not only servers contain valuable data.
