Linux NFS always has had very poor performance wrt local filesystems, but
adding another layer of complexity in updatedb to overcome the limitations
of NFS over slow links is inappropriate.

The NFSv4 spec allows very aggressive client-side caching.  Recent kernels
with cachefs may even use local files for backing store.  This general
solution should speedup most usage patterns without the need to add
specialized caches to all applications.
