About mounting and unmounting NFS filesystems

A client can mount a filesystem in four different ways:

automatic mounting at system start

The system administrator of a client machine can configure the client to automatically mount remote filesystems every time the client machine goes to multiuser mode as described in ``Modifying filesystem mount configuration''. Remote filesystems are unmounted whenever the system goes to single-user mode.

administrator manual mounting

The system administrator of a client machine can manually mount remote filesystems at any time using the mount(1M) command.

user mounting

The system administrator of a client machine can authorize users to mount remote filesystems when they need access to them by assigning the Administer Filesystems authorization. See ``Assigning authorizations''.

automounting

A client machine can be configured to automatically mount remote filesystems when a user executes a command requiring access to those files. The mounted filesystems remain mounted until a preset period of inactivity has passed. At this point the client automatically unmounts them. See ``Using the NFS automounter''.
