Mounting and Unmounting Directories
NFS clients can mount any filesystem or a part of a filesystem that is
shared by the NFS server. Filesystems can be mounted automatically
when the system boots, from the command line, or through the
automounter. The different ways to mount a filesystem are as follows:
• Mounting a filesystem at boot time and using the mount command
For information on how to mount a filesystem at boot time, see
“Mounting a Remote Directory on an NFS client” on page 78.
• Mounting a filesystem using an NFS URL
For information on how to mount an NFS filesystem using an NFS
URL, see “Examples of NFS Mounts” on page 80.
• Mounting an NFS filesystem through a firewall
For information on how to mount an NFS filesystem through a
firewall, see “Accessing Shared NFS Directories across a Firewall” on
page 65.
