My experience, admittedly from a few releases ago, is that ifupdown is always installed but that the installer doesn't populate it's config files with the found network interfaces, only the loopback interface. I also have a more vague memory that you could put config into /etc/network/interfaces then in some circumstance NetworkManager would not try and manage that interface, and in others it would take over. (Perhaps selected by allow hotplug option in the ifupdown config?) -- Tixy
