Unmount drives before closing PPTP vpn

["mr wizard" <mr wiseman gmail com>]

Hey guys,

I'm running Ubuntu 7.10 at the moment and I'd like to unmount some
network drives when I close my PPTP VPN connection. I found
NetworkManagerDispatcher, but that doesn't seem to care about VPNs or
ppp connections at the moment.

Am I missing something, is there another way to do this or should I
just wait until it gets fixed?

I have looked at the code but I got lost pretty quickly between the
different daemons, programs and plugins (also, I've never worked with
DBUS).

Regards,

Ronald
