It would be really cool if useradd, etc. knew about zfs, for this.

Yes, yes, yes!! +1 million.

I'd love to ditch the use of ufs entirely in favor of zfs, but right now 
it is too painful to do this out of the box.

? Some of this is what NWAM does, but I'm not sure about other stuff.

Yes, I think SMF, or SMF with profiles ala NWAM, is better here.

Yes.   But lets expand this to SDcard as well.  (What about ZFS on 
non-disk media, such as memory cards?)

I'd like to see more flexibility in upgrading zfs pools to increase 
redundancy or grow them.  E.g. if I a have a pair of disks in a mirror, 
it would be cool to be able to increase the size of the pool by adding 
another pair of drives.
