The kernel has to do RPC over UDP/IP for NFS accesses, so some files
are needed there.  More files are needed to do RPC for general user
level applications, and they live in the libraries.  The common files
in the Sun NFSSRC reference port are identical; our revision control
system has links in some underlying directories to ensure that the
changes made are made to both kernel and user level code.
