[Pkg-utopia-maintainers] Bug#688355: network-manager: NM breaks /etc/network/interfaces with DHCP + manual IPv6 entries created by wheezy's debian-installer

[Raphaël Hertzog]

Package: network-manager
Version: 0.9.4.0-6
Severity: grave

I just installed a new laptop using wheezy's d-i. I do have IPv6 on the
network and as a result d-i did output supplementary entries in
/etc/network/interfaces.

However NetworkManager garbled them and the result is a file that
ifup doesn't parse. The net result is that the loopback interface
is not configured... and random things that don't work with hard to
debug failures.

$ cat /etc/network/interfaces
# 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
# This is an autoconfigured IPv6 interface
#NetworkManager#iface eth0 inet6 manual
	up ip link set eth0 up
	down ip link set eth0 down

Either NM needs to learn those new entries or we need to find a
definitive solution...
