ZFS.

[Naoki]

Seems ZFS is out in the wild under the CDDL ( implications of that
license I have no idea of though ).

And the linux port is underway? :

So does anybody know if the CDDL restricts the ability for it reaching
the main kernel?   And anybody else think it would be a really cool
addition?
