Examples of NFS Mounts
• Mounting a directory as read-only with no set userid privileges
mount -r -o nosuid broccoli:/usr/share/man /usr/share/man
In this example, the NFS clients mount the /usr/share/man directory from the
NFS server broccoli. The local mount-point is also /usr/share/man. The
directory is mounted as read-only.
Figure 2-3 illustrates this example.

• Mounting a Home directory
mount -r -o nosuid broccoli:/home/broccoli /home/broccoli
mount -r -o nosuid cauliflower:/home/cauliflower /home/cauliflower
In this example, the NFS client mounts the home directories from NFS servers
broccoli and cauliflower . The nosuid option prevents programs with setuid
permission from executing on the local client.
Figure 2-4 illustrates this example.
