Then perhaps you are more interested in a structure like the one
postgresql uses, where there is a namespace in /etc and /var/lib for the
specific instance of postgres. All, however, are run as the same system

Also, I'll note that a well designed packaging system should _never_
blindly overwrite already existing files in /etc, so I would implement
your case as:

* Install predefined configuration files in /etc
* Install daemon package
