With the patch "[PATCH]udev:Extend udev to support move events"
(http://marc.info/?l=linux-hotplug&m=125673399217656&w=2) udev would be
able to handle "move" events that are generated when interfaces are
renamed by commands like nameif. And we can maintain the symlinks by
having rules to handle this move event.
