The only thing that needs fixing for NM would be changing the
nm-system-settings.conf file from ifcfg-rh to keyfile. Is NM still
forked for F14?(haven't checked) If is is then I don't think os-builder
is the issue in this one, but I'll do a quick sed fix for now.

Yes, think that would be a good idea, with this method connections.cfg
can be empty. Perhaps network.py can just use/create the needed file
for /etc/NetworkManager/system-connections/ or make that an option
available in control panel.
