[Pkg-utopia-maintainers] Bug#907747: Bug#907747: network-manager manages interface managed by /etc/network/interfaces

[Arian Sanusi]

to put my paint point first, maybe it was not clear: at boot NM does not connect at boot to a WiFi. Instead I have to click the applet, wait multiple seconds for a scan to finish and then have to choose the wifi manually. NM says it would be connected to my bridge, see attached screenshot.

^ this, at least sort of: it behaves like the presence of the bridge is enough, while the bridge can't give me internet access. It doesn't change bridge's settings AFAICT
> Or are you expecting NM to manager your bridge interface but it does not?

thanks for this suggestion, I'll try it! however I still think theres something unnecessarily annoying that should be fixed, especially when docu suggest that ENI was enough.

the lines from the log that read wrong to me:
 
> <info>  adding bridge port none to eni_ifaces
none is a special value indicating an empty list that I guess the parser does not handle. If this was python it would be "bridge_ports = []"

> <info>  devices added (path: /sys/devices/virtual/net/bridge, iface: bridge)
> <info>  device added (path: /sys/devices/virtual/net/bridge, iface: bridge): no ifupdown configuration found.
I can't find another explanation for this as that the eni parser is wrong

> <info>  device (bridge): Activation: starting connection 'bridge' (92896f34-0c23-4893-a459-7bf9f941f397)
if this is not saying that NM does something about the bridge, then it's misleading.
