Just to be nitpicky (or something): should that really matter?  I've been 
doing it as root, and am now successful reading and writing under my userid 
(while using no_root_squash)--will I be unsuccessful if if I switch to 
root_squash and still do the mount as root?  (I presume that during a boot, 
mounts are done by root.)

I understand the above, but as stated/implied in the first comment above, 
would be surprised/disappointed if mounts during boot did not work properly.

That's helpful.  In the other reading I had done I hadn't found anything about 
how to masquerade as a different user in NFS--I don't read manpages as often 
as I should--it used to be because they seemed like greek to me--now more of 
them make sense--I just need to start reading more of them.
