Comment 144 for bug 211631

On a functional level perhaps it is worth considering whether Network Manager, on stopping, should simply leave the interfaces as currently configured instead of taking them down. I can make the argument that Network Manager is a tool to make it easy for the user to control network interfaces, but Network Manager is not the owner of those interfaces, the system and user are. If the user makes a connection using Network Manger and then disables NM, why shouldn't the interface stay up until the user or a shutdown sequence takes it down?
