Ok, makes sense.  So I need to re-think this.

What I don't understand right now is: how do I create these "übergeoms"?
The problem I'm faced is this: I need to keep a copy of the vinum
configuration somewhere where it isn't touched by an occasional orphaning
and self-destruction massacre when a disk fails.

My idea was to have a separate class VINUM that just holds the config, but
isn't actually connected to the I/O path, so the other vinum geoms (for
volume, plex, a.s.o.) could peek at the config and decide what to do.

Pointers into the right direction are highly appreciated.
