I've heard this stated before, and it doesn't match my experience. On
my Solaris systems, I routinely list hostnames in the exports file
(actually, /etc/dfs/dfstab) in all lowercase. Yet a reverse lookup of
any of my clients' IP addresses returns a mixed case
"host.Berkeley.EDU" result, and all my NFS mounts work.
Note: if you use NIS or NIS+ it may be a different story; I haven't
used either in several years.
