ZFS in Update 6/06

At last i can write about it. ZFS will be part of Solaris 10 Update 6/06. I use ZFS for quite a while on my home fileserver and it´s really cool. Even for a home user. This filesystem is a large step. From empty new disks to full functional filesystem in 2 (maybe 3) commands. Snapshots that doesn´t eat away you disks. Selfhealing after replacement of a corrupt disk with detection of the correct mirror. On-the-fly-Compression. Rebalancing of data in case of pool extensions.
Before writing something like “you find this in xFS, too”: Real all documentation you find about it. Think about it. And than think about the following question: “Is it really the same? Do you find all features of ZFS in another filesystem?”
