First, I haven't actually tired this yet, as I haven't had time to
install F9 on any of my machines.  But I will have a chance sometime
soon, maybe this weekend.

nm-applet doesn't start until you log in, but NetworkManager starts at
boot if it is set to do so.  My understanding is that NM (the service)
should start an interface at boot if ifcfg-<device> is set up correctly.
It's likely that mobile users wouldn't want an interface to come up if
it wasn't under their control (through nm-applet).

I think I've seen that the NM service will be set to start earlier in
the boot sequence in a soon-to-be-released update.  The longer-term
solution would be to have services that require a network understand how
to wait for one to come up (through dBus, for example).
