Hi Shawn,

My initial idea is to have /home/ja/bin files
available for cron or for me, when I'm working on
the rh 8 or 7.2 boxes.  Also, I want access to
'common' config and logfiles on the box that
exports /home/ja/etc.

As a novice with nfs, it seems better to avoid
messing with the dot files rather than controling
  the dot file problem.

And, I don't want to reinvent the wheel.

Here is an example of the differences when
mounting the export, as opposed to not mounting
the export: 

With it not mounted, I can click 'hat' and 'log
out' and exit X immediately, with no intermediate
prompt.  With it mounted, there is an
intermediate prompt.  

Obviously, I don't care much about the extra
prompt, just that it tells me that the desktop
config has changed.

I sure appreciate your comments and hope that
others may have another perspective.

Thanks,
Jim
