    There is something weird going on when sysfs directories and symlinks
    are renamed. My guess is that I fat fingered something with one of my
    last sysfs patches. I will look more deeply once I have slept some

    The second network device renames fails because the first rename did not
    work properly. ls -l /sys/class/net/ /sys/virtual/net/ will let you see
    what I mean.
