    Don't think you need both auto and allow-hotplug.

    "auto" means interface should be started when 'ifup -a' is run
(during init); "allow-hotplug" means it should be started when a new
interface is connected to the system (in relation with the system's
hotplugger, udev/eudev).

    Since there is no udev event for the loopback inerface, "auto" is
necessary for this one.
