Hi Philipp et al,
my first idea to address this issue, was to modify/patch NM to not
deconfigure the device when NM is stopped and make it possible for NM to
pick up the existing connection when NM is started again (that's also
the reason why I merged 432322 and 433087, as it would have solved both
issues).
I talked about this with upstream, and he said for connections like
ppp/vpn/wireless it would be almost impossible, for ethernet connections
maybe but also only with considerable effort.

I will take this approach for now: restart NM in postinst (instead of
stop in prerm, start in postinst). I'll do the same for dbus.
This should minimise the downtime and in case the upgrade process get's
interrupted in between keep the machine accessible via the network.
It's not a perfect solution but I hope RMs will consider it appropriate.

As said, I first wanted to address this differently. For now I unmerged
the bugs again and will handle them separately.
Cheers,
Michael
