Yes, but the problem that occurs is uniquely identifying a domain. In
other words, what's the key used within the persistent store?
If it's domain id (which is what I assume it's going to be), you cannot
tag it as having an "inactive" state because there's nothing that
prevents a domain from being created with the same domain id.
Also, if you try to assign domains UUIDs or something, what do you do
for cloning/checkpointing? Do you assign a new UUID on a clone but not
on a checkpoint? Does assigning new UUIDs propagate to things like MAC
addresses or other things that are supposed to be unique?
There's a lot to be thought about. I think punting the problem (as Andy
suggests) is the right approach for now.
