Quoting Tycho Andersen (tycho.andersen at canonical.com):
> This was originally used to propagate the bridge and veth names across
> hosts, but now we extract both from the container's config file, and
Is that the right thing to do?
> nothing reads the files that dump_net_info() writes, so let's just get rid
> of them.
