Ticket: none Reviewed By: trivial Testing Done: installed, Alex tried for image creations. apparently with some of our packages like mstpd still using init.d for a while longer, just having the init.d/networking file causes the original complaints about loops between services. So I'm purging it completely. Also clean up the comments a bit in start-networking
