Okay, on "tiny", files on the partition should have UID 501, GID 82, and 
umask 000. Is that what actually happens?

NFS communicates file ownership using UID and GID numbers, not names. On 
the host "oracle", what UID is "nobody"? What GID is "users"?

Your "mount" command there looks like it was done as a normal user. If 
you perform the mount as root, do the perms come out differently? FWIW, 
for ongoing use you're better off using an automounter such as amd, 
rather than putting it in fstab.
