That's the case for 99% of the features and semantics we have: 
by definition a single-purpose device uses only a small sub-set 
of an infinite purpose OS, right?

Still we only modularize semantics out if they easily fit into 
some existing plug-in/module concept, if the feature is arguably 
oddball that a sizable portion of people want to disable, or if 
it makes notable sense for size reasons. To me it looked 
distinctly silly to complicate things for such a small piece of 

I doubt Kees would mind modularizing it, but it would be nice to 
get VFS maintainer feedback in the:

   { 'you are crazy, over my dead body' ... 'cool, merge it' }

continuous spectrum of possible answers.
