This is partially true.  When NFS goes across the wire to the server
machine, it goes as "root" (/usr/ucb/{rlogin, rsh} are setuid "root"). 
NFS maps "root" to the userid "nobody" on the server machine, and "nobody"
is usually a non-privileged userid.  Since the .rhosts file is not (or
shouldn't be) readable by the world, a non-privileged user cannot look
at the file.  This is what is causing the failure of "rlogin" and "rsh"
for those users that have read permission (on their .rhosts files and/or
home directories) denied to others.  One workaround is to give world
read permission for .rhosts, but this isn't suggested as it could
compromise security.

The solution is not to have the client machine look for the .rhosts file 
as "root", but as the user in question.  This is currently an outstanding
bug against Dynix.
