Yeah, in my howto I'm using the meta volume that ctdb uses for its lock 
file to also store the config files for ctdb, and that's what selinux 
doesn't like. It's not really necessary, though, the configs could just
be copied into the default locations on each node -- I think that would
resolve the selinux issue.
