FYI, you can use Network Manager and /etc/network/interfaces together w/o
problems. I run sid, but I've been using this setup for some years now,
so I would expect it to work on stable and testing too.
>From /usr/share/doc/network-manager/README.Debian:
-------------------------------------------------------
...
Devices listed in /etc/network/interfaces _will_ be managed by NetworkManager
unless the ifupdown system-config-setting is enabled and is setup to run
in "Unmanaged mode".
The config to select unmanaged/managed mode is in
/etc/NetworkManager/NetworkManager.conf:
[ifupdown]
managed=true/false
...
There are plugins for different configuration sources.
By default the ifupdown and keyfile plugin are enabled, see
/etc/NetworkManager/NetworkManager.conf:
[main]
plugins=ifupdown,keyfile
The ifupdown plugin is read-only and reads the native ifupdown configuration
file /etc/network/interfaces.
-------------------------------------------------------
For example, on my system I have my wired interface settings in /e/n/i
and I change my wireless settings through the NM gui in Gnome.
When I plug in the cable, the /e/n/i setup is activated (static IP and DNS),
and when I choose wireless in the GUI, the wireless settings are used
(static or dynamic depending on the wireless network).
My /etc/NetworkManager/NetworkManager.conf file has:
-------------------------------------------------------
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=true
-------------------------------------------------------
(I also have dns-nameservers lines in my eth0 stanza in /e/n/i.
IIRC, when I didn't, using dynamic wireless connections kept clobbering
the static DNS entries in /etc/resolv.conf.)
