Yes, NetBSD has these, but it's a lot easier on ZFS. As an example, I
don't have to worry about shrinking or growing partitions, because they
are all pulling space from a common pool. I haven't used fss(4) yet,
but ZFS snapshots appear to be a lot more powerful. I use zfs clone and
zfs send/recv extensively.

On the other hand, ZFS on anything other than Solaris has always felt
like a square peg in a round hole. I think it makes a lot more sense to
put energy into porting Hammer. This gets us a filesystem with a future
that can be controlled and guarenteed, as well as integrating cleanly.
