Not on my machine.  NetworkManager and network are not designed to run
at the same time. It is not clear what NM would do in run level 3
without X. You certainly don't have a nm-applet running at rl 3 in any
meaningful fashion.

Look you talk about rc3.d but if you are using nm-applet you can't be at
run level 3 so what is in rc3.d is irrelevant. We are having a giant
miscommunication going on . What rl are you actually running at?
