Ah, grasshopper, you've discovered one of the seventh wonders of the 
world -- the 'masking' effect when one filesystem is mounted on top of 
another.  :-)

You can get the same effect with any mount, local or nfs.  If you fill 
/usr/local with stuff, then mount some other partition on 
/usr/local, you now have access to the stuff on the new partition -- 
but the stuff on the "real" /usr/local is hidden, inaccessible to you 
or anyone else until you umount the mounted filesystem.  It's still 
there, obviously, as you saw ... there's just no access path to it.

So if you want, as I do, access to a skeleton home directory on the
client, while still having access to your data on a /home server, you
need to be more creative.  I mount atlantis:/home on
littleblue:/mnt/home, and then put a symlink to /mnt/home/dtalk at
~/atlantis on littleblue.  I can then get to my data via that link, 
without obscuring the local files and configurations on the client.

Does that help?
