Because 'fs' never makes RPC's -- it only makes calls to the cache
manager, which does operations based on a fid.  I suppose you could
arrange things so that the 'vos' command constructs an appropriate fid and
calls the fileserver directly, but I'm not sure it's a good idea (or even
possible, in the current structure) to introuce a dependency in volser on
the fileserver interface.
