It is a bit convoluted, and I'm well on my way to having a (much simpler)
upstart configuration to accomplish this.  I intend to set up the following

- eucalyptus (cloud, walrus, sc -- the bits which run in-process)
- eucalyptus-cc (the cluster controller)
- eucalyptus-nc (the node)

For the first one, it seems that I need to pass "--disable-foo" if that
component is not installed or should not be started.  There are also
--remote-foo options.  What do those do?

I intend to do the registration at package installation time, rather than
when the service is started, so that package dependencies handle the
ordering for us.

The only possible snag I see with this is that we're determining the IP
address to use at registration time, so if the service moves to a different
host, we won't handle that automagically.  I think that's probably OK for
the moment.

My main unresolved issue is what to do about autoregistration of the nodes.
How do you suggest we handle that?
