I don't like this design decision either. I have a couple of ideas on how
to get rid of rcorder completely and bring the dependency checking into
the script itself (complete with the notion of hard and soft
dependencies).

I was thinking of coming up with a way to make dynamic dependency 
registration and coming up with a reverse and forward dependency tree so 
if you stop nfsd, it would make a call to mountd to see if there was 
anything still using nfsd. If there weren't any more dependencies, it 
would then stop mountd (that could be a bit risky though, depending on the 
completeness of the dependency tree).
