    I disagree (not surprising :) completely. The well-known userspace
    tools (ifconfig, ip, etc) will not see the lo@1, they'll see lo.
    Userspace in a container can either umount /sys completely, or do

    mount -t tmpfs none /sys/class/net
    mount --bind /sys/devices/virtual/net/lo@1 /sys/class/net/lo

    if they really want to, in which case only their view
    of /sys/devices/virtual/net would be different.

    Eric, would you hate this less if it was under some


    config variable?
