No, Btrfs is still not production worthy. But ZFS is not either. It is 
still missing a lot of stuff, and stability??? I do not think so (This 
is only what I have read about it). I should have been more clear, I 
think Btrfs will much faster reach it's goal, since both Oracle and (Red 
Hat) want it as their default FS, as soon as possible.

At the moment, if you want ZFS you better install Solaris.
