# Example /etc/exports file taken from Ultrix 4.2 man pages for "exports".

/usr alpha beta         # export /usr to hosts alpha and beta, client
                        # superuser maps to uid -2 and read-write
                        # access is permitted

/usr/staff/doe clients  # export directory to hosts in netgroup clients

/usr/man/man1 -o        # export directory read-only to everyone

/usr/local -r=0 beta    # export file system to beta, superuser
                        # on beta maps to local superuser (uid=0)

# Question: Is the first entry above (with root mapped to uid -2) secure?
# Answer: Can root change their uid on the client system to be anything
# they want? (Read "Managing NFS and NIS" for more details on NFS security).
