Subject: Namespaces and devices

Hi,

Sorry if this is a dumb question, but I couldn't find any
documentation that matches the current behaviour... So I don't know if
what I see is what is intended, or if it's a bug.

I would like to know what is the exact behaviour re. devices when a
netns is destroyed, and which kind of devices can be moved.

According to http://lxc.sourceforge.net/network/configuration.php,
devices assigned to a netns should move to the main netns when the
former is destroyed. What I see is that the devices are deleted, at
least for veth and dummy devices. I also see a bug I previously
reported that caused an oops in some cases.

Also, I have read somewhere (now I cannot find it) that supposedly, I
should be able to move real devices to a netns, but I always get
Invalid argument errors.

Thanks.
