rules sort order: /lib, /run, /etc
After long consideration we came to the conclusion that user configuration in /etc should always override the (generally computer generated) configuration in /run. User configuration should always be what matters over anything else. Hence rearrange the search orders accordingly. In general this should change very little as overriding like this is seldomn done so far, and the order between /etc and /usr stays the same.
