[Pkg-utopia-maintainers] Bug#642191: network-manager: On upgrade/restart, resolv.conf is overwritten with empty file

[Hilko Bengen]

Package: network-manager
Version: 0.9.0-2
Severity: critical

On my workstation, I have a fairly trivial network setup that just used
to work:

,----[ /etc/network/interfaces ]
| auto lo eth1
| 
| iface lo inet loopback
| 
| iface eth1 inet dhcp
| 	hostname ataraxia
`----

isc-dhcp-client is installed. When ifup is called, the DNS information
from the DHCP server is correctly written to /etc/resolv.conf (At the
moment, I am not entirely sure what component is responsible for this on
my system, but I have been able to reproduce it by calling ifdown eth1;
ifup eth1.)

When network-manager was upgraded to 0.9.0-2 last night, the daemon was
restarted and in the process overwrote /etc/resolv.conf with the
following single line:

,----
| # Generated by NetworkManager
`----

As one may expect, this breaks DNS for the machine. I am filing this bug
as critical because I consider this behavior as making "unrelated
software on the system (or the whole system) break".

The output of "grep NetworkManager" over yesterday's syslog is attached.
I hope it will be useful.

Cheers,
-Hilko
