its not.  and, afaik, the linux implementation of ZFS is not very well 
supported, I certainly wouldn't commit to a project relying on it 
without a LOT of testing.   ZFS is very stable on Solaris, and I 
understand its working quite well with FreeBSD

Supposedly the new btfs for linux will be the choice.  i'll remain 
skeptical of that until its proven itself in varied production 
environments by others.
