 - a MAKEDEV run is something one does (usually) once only, so
   optimisation for speed is not the primary goal here
 - if anything, the test-file should not be generated in /tmp (or some
   possible netboot-server!), but in . (the new /dev), preventing to
   overwrite anything without a real need. 
 - i think another portable solution would really be to just split this
   into seperate chown & chgrp commands. One could do this with the aid of
   some shell function, but I'm not sure how portable that is.
