If you'll neither believe me nor the code wrt causes these 'random
device names', may I try some kind of authority?

    7.4.3.7. Device naming order changes randomly after rebooting


    This is due to the fact that Udev, by design, handles uevents
    and loads modules in parallel, and thus in an unpredictable
    order.
