The problem referred to in the release notes is not with NFS, but with
RFA (netunam).  I am running 6.5 on my cluster and just confirmed that
csh starts up just fine when my current directory is under an NFS mount point.

I believe the passage in the release notes you're referring to is the
following one:

                  It is no longer possible to start "csh(1)" when the
                  current directory is on an RFA-connected file system.
                  Both "sh(1)" and "ksh(1)" will start properly in a
                  remote directory.

RFA is the name of the HP-proprietary transparent remote file access
system (accessed via the netunam shell builtins and the netunam system
call).  It does not refer to NFS.

Since the problem is with RFA and not NFS, you should not have any problem
with your configuration.  By the way, the bug is supposed to be fixed in
a forthcoming release.
