Subject: HP-UX 6.5 NFS problem on cnodes. (A help question -- 2 pages)

We have an instructional lab which has 2 clusters.  Each file server is a
9000/350 and the cnodes or 320s.  There are 9 cnodes per cluster.

Currently, we have user's files cross mounted between clusters.  i.e. cluster A
user files are remotely mounted on cluster B and cluster B user files are
remotely mounted on cluster A.  Thus, if a user logs onto a machine, his/her
home directory could very well be nfs-mounted.  So far, this has worked fine.
 
However, we are planning to upgrading from HP-UX 6.2 to 6.5 very soon.  We
discovered in the release notes a very serious problem.  Apparently, if you are
logged in on a cnode and your cwd is an nfs directory, you can not start up csh.

This would seem to indicate that we would no longer be able to cross-mount 
these user files.  Because of the configuration of the clusters -- software
availabillity and so on -- this is highly undesirable.

I realize that I could give each person a local home directory on
each machine.  However, can anyone suggest another work around for this problem?
