NFS mount issue

[Darryl Moore]

I'm building the script to do this and one thing occurs to me. What
about when someone who does not have a local account on the laptop tries
to log in? The machine will let them log in, but will not be able to
find their home directory.

A union mount might be interesting, but you'd want (rw) on the local
home for users with local logon and (rw) to be on the network home for
other users. So I don't think this will work. sigh. There should be a
way to do this.
