Unfortunately this isn't the end of the matter. Udev doesn't appear to
wait for the device to be created before it forks the RUN command and so
you get random 'no such file or directory' errors.
Does somebody who understands udev better than me know if there is a way
to get udev to serialise properly? I'd rather not do it the hard way
unless I have to.
