[Pkg-utopia-maintainers] Bug#755202: NetworkManager creates broken eth0 connection while booting

[Frederik Himpe]

I'm seeing the same problem: every time I boot my system, a network
called "eth0" with disabled IPv4 and IPv6 is selected.

My NetworkManager.conf looks like this:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

/etc/network/interfaces looks like this:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
#NetworkManager#iface eth0 inet dhcp


I have removed the broken eth0 connection in NM, leaving only the
working "Auto Ethernet" connection. Then I ran 

# service network-manager stop && NetworkManager --no-daemon --debug

This did not create the broken eth0 connection:
# nmcli c show

Suspending/resuming my system did not create this connection either.

However, after a reboot, the broken eth0 connection was there again.
