So, for example,
you could type:
# mount /oak/apps
With this command, mount knows to check the /etc/fstab file to get the file system to mount
(oak:/apps), the file system type (nfs), and the options to use with the mount (in this case ro

for read-only). Instead of typing the local mount point (/oak/apps), you could have typed the
remote file system name (oak:/apps) and had other information filled in.
When naming mount points, including the name of the remote NFS server in that name
can help you remember where the files are actually being stored. This may not be possible
if you are sharing home directories (/home) or mail directories (/var/spool/mail). For example,
you might mount a file system from a machine called duck on the directory /mnt/duck.
Using mount Options
You can add several mount options to the /etc/fstab file (or to a mount command line itself)
to influence how the file system is mounted. When you add options to /etc/fstab, they must
be separated by commas. For example, here the noauto, ro, and hard options are used when
oak:/apps is mounted:
oak:/apps /oak/apps nfs noauto,ro,hard 0 0
The following are some options that are valuable for mounting NFS file systems:
hard??”If this option is used and the NFS server disconnects or goes down while a
process is waiting to access it, the process will hang until the server comes back up.
