IMHO, if you want to be able to dynamically enable/disable subsystems
based on dependancies, you need to keep track of which ones are
currently running.

I think this would be best done using a different model for starting
daemons/subsystems, more akin to an inetd/init model (where a
management daemon remains as a parent to the managed services) as
opposed to an rc "fire and forget" model.
