Indeed. The thing here is that if you limit the rollback scope to just 
config files, things suddenly become far more manageable. It wouldn't cost 
an arm and a leg to (optionally) store the entire config file history 
separately, say, in a real SCM or something resembling one.

Imagine being able to diff the config files between this and the previous 
(or a year ago) version, or what's currently on the system vs what the 
package contained when originally installed. Etc.

I'd guess that quite a few sysadmins would just love that...
