I don't get this: it seems normal to me that the interface would be down until it's 
configured by the container, pretty much like on a normal machine. The only situation 
in which you can expect an interface to be up already is in a network-booting situation, 
in which the initramfs configures the interface. In a virtualised situation, this is like the 
host configuring the container's interface for it.

Anyway, no big deal either way for me.
