Comment 9 for bug 262817

I have this same issue. Updated a machine from Hardy and Networkmanager died, or rather DHCP. Managed to get online with hard coded IPs and find this report. :)

"properly clean your changes and get the maintainer shipped config files in place" is not much of an instruction though, especially since I haven't edited those files, ever, even though I suppose some package I installed during hardy might have.

Anyway, adding the root entry seems to fix it. Is there a better way to properly clean and getting in place?
