Nope.  I had read that as meaning you didn't want to keep changing the
selection in the policy for updated snapshots (like backup.yymmdd), not
that changing it as filesystems came and went was the issue.

If you're just worried about the hands-on work, it could be scripted.
There's a few situations I've had where a static configuration just
wouldn't work (usually involving netapps and snapshots made by another
application that didn't want to be controlled).  So I ran a script daily
that modifed the NBU configuration.  Here, it could poll for zfs
filesystems and make sure they (or a valid snapshot) are in the bakcup
selections list.

That still leaves the extra communication necessary to support the
script though.  I'm just not sure what else you can do without more
explicit support for ZFS within the client.
