In that case it seems that the only reason for the existence of the NetworkManager daemon is to perform the required privileged operations at the biddingI don't know *exactly* how NetworkManager works, but I'm under the impression that it only holds a network connection while the applet is running, i.e., while the user is logged in. This could be a security thing, because it gets the network settings from the user's settings, and also the authentication to a wireless network are taken from the logged on user's key ring. So it's actually quite logical that it would shut down the network at logoff, BEFORE any of the shutdown scripts run. (In that case it seems that the NetworkManager daemon is only there to do the required privileged work at the bidding of the nm-applet. And if the nm-applet disconnects due to logoff, then it disconnects...) Anyway, this is all just conjecture. I might have it all backwards.
