And to make matters worse, you can failover a master/master cluster, or
a media/media cluster, but you can't fail over a master/media cluster.
i.e. we want one node to be a master/media server, the second node to be
just a media server and to pick the master functionality if the master
dies.  I don't think that there's any way of doing that.  Sun V490 with
Solaris 9 currently 5.1MP4 with 6 probably when MP2 comes out.
SAN-attached storage (which is where /usr/openv is currently).

We'd really like an active/active cluster config...
