13:59 < dcbw> dgilmore: the code is icky but the concept is sound; NMD will call scripts in /etc/NetworkManager/dispatcher.d/ whenever an interface goes up or comes dwon
13:59 < dcbw> dgilmore: however, be aware that when your script gets called when the interface comes down, it's _already_ down
14:00 < dcbw> dgilmore: the script will get two arguments; <ifname> <up|down>
14:00 < dcbw> dgilmore: or something like that.  make sure the script is executable only by root
14:02 < dcbw> dgilmore: see http://gentoo-wiki.com/NetworkManager
