the idea of snapshot was to just get a portable list of packages and per-package 
configuration for backup purposes (or even cloning) without adding too much 
overhead.

Adding moonbase to this is silly: in case I want to add another server 1 year 
later with the same packages, getting a one-year-old moonbase is not what I want...

those should be lvu submitted anyway :)

OK, this might be something we can add to the snapshot (makes sense)

there are better tools for this. restoring stuff from /etc/ in luar is extremely 
dangerous and guaranteed to muck up module upgrades. I would stay away from this 
  if I could.

if you like *BIG* snaphots... shrug. Try using a real backup program instead!
