        Advantages over 'ifrename' :
-               + integrated into 'udev'
                + simpler to setup if 'udev' is already properly setup

        Drawbacks compared to 'ifrename' :
                - Less selectors that 'ifrename'
                - Require kernel 2.6.X or later with sysfs support
                - Do no support non-hotplug interfaces
                - Require 'udev', not everybody uses it (static /dev, devfs)
-               - Does not support module on-demand loading

 virtual devices, such as tunnels and loopbacks, are not associated
 with a hardware bus, and therefore are not managed by hotplug. All

                o It is common practice on embedded system to use a
 static /dev and not 'udev' to save space and boot time. And to not use
 hotplug for the same reasons.
