	It's not made immediately clear in the documentation but you can
use a hammer filesystem as a replication master instead of a PFS. My /home
is a hammer filesystem on it's own partition replicated to a PFS in another
hammer filesystem on a different disc.

	One thing that does trouble me a little is that the nullfs mount of
the slave PFS is frozen while the nicely named symlink is not. The nullfs
mount to the slave would be much more useful if it was not frozen, as it is
I reverted the mirror-stream operation to refer to the PFS symlink and I
don't use the nullfs mount at all for the slave PFS.

	I'm still trying to work out the logistics of doing a remote
mirror, it seems to me that it should require root at both ends and I'm not
entirely happy about opening up root ssh.
