Comment 5 for bug 882093

I don't see how this would be related to whether networking is an upstart job or not, anyway, as of 12.10 it'll only be an upstart job.

The most likely problem is that networking is also bringing down the loopback device which I'm guessing part of the desktop uses for obscure reasons, that's indeed a problem but not something we should try to fix in netbase/ifupdown.
