Hmm, that wouldn't be possible without a more complex script, since that
depends on specific state.  NM doesn't signal the script whether the
disconnect was user-triggered or a failure of some kind, although NM
does have that information internally.

If you wanted to do that now, you'd write a small daemon that listens on
D-Bus for the NM device state changes events, which include a result
code that tells you what the disconnection reason was.  The small daemon
could then do whatever it wanted to do with that information, and you
wouldn't need a dispatcher script at all.

Dispatcher scripts are simply kludges for stuff that can't talk D-Bus.
At a certain point, if you require functionality that's not reasonable
to implement in the dispatcher script case, you'd probably be better off
listening to dbus with a small daemon, because then you have the full NM
API to work with.

In the end, we just need to make this work within NetworkManager.  It's
something people have been requesting for a while.
