Hi Jens,

I believe the shortest path to success here is to do RUNLEVEL=DEV and make
it NEEDS=devices (and anything else you need before it runs).

Seth

p.s. did you mean to use three different methods for invoking stop and start
in reload and reload in restart?  You might want to check that you didn't
make a typo, too. :)  You normally don't need to specify reload and restart, 
btw. I think you might just need a start() function here and it would work 
fine.
