retitle 562748 NetworkManager with disabled ifupdown plugin doesn't work correctly anymore
thanks

I just tried the newer NetworkManager packages in testing and unstable
and hit the same problem. The problem is that it changed the hostname
of the system (resulting in X not working anymore):

Feb 28 10:55:05 runge NetworkManager: <info>  Setting system hostname to 'dhcppc0' (from DHCP)

Other than that, it also changes /etc/hosts by adding that hostname to
127.0.0.1, resulting in that the reverse DNS of 127.0.0.1 is dhcppc0
instead of localhost:

127.0.0.1       dhcppc0 localhost.localdomain   localhost

I'm really wondering how someone can think that letting NetworkManager
change these things can ever be a good thing. Anyway, I started to
look why this happens on my system and not on other systems. It turns
out that the problem is that I disabled the ifupdown module in the
past, when I enable it again in
/etc/NetworkManager/nm-system-settings.conf all problems go away.
