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.
