(Which happend on July 9th, cf. #633306 for the details). So somehow the install created the wrong symlinks and sysvinit did not change them because it assumed the transition to be over, I assume? Cloning to sysvinit to get the best course of action.

Probably related to my other changes. (Btw.

Unless I hear otherwise, I'll try to manually switch the symlinks around and see how it goes. Thanks again *very much* for your help!
