You have kind of answered your own question here. If you need root
access to the files from the client, you will need the 'no_root_squash'.
All that option does is honour your clients root user over the NFS share
(not great for security but I don't know your set up details).

Other than that you'd have to manage the users on both systems, to be
the same name/uid/gid etc.. and do everything as a non-root user (better
for security).

Take a look at this link[0] and hopefully that should clear it all up.


Thanks,
Michael
