I guess I am the last one on this planet but it’s done: tiny little server at home updated to Debian 7.3 Just to the records: this short german howto was helpful, the Upgrades from Debian 6.0 chapter and I learned that realtek NICs aint free.
system maintenance for the next 5 years: done.
UPDATE: so I also moved from SysV init to systemd. nothing special as the move is well documented switching some services off and looking at systemd and how to debug it helped a little to get everything clean again.
