Right.

create-cluster just creates the configuration information for the
cluster in domain.xml. It doesn't do anything for any servers that
want to be part of the cluster. But once that is done, a machine
that wants to run a server that's part of the cluster should be able
to issue appropriate commands to "join" the cluster. We've been talking
about what these commands should do and I think we've got it figured out.
I need to update the design spec with the information.
