How does the NFS Automounter help to improve the performance and scalability of NFS?
What will be an ideal response?
The NFS mount service operates at system boot time or user login time at each workstation, mounting
filesystems wholesale in case they will be used during the login session. This was found too cumbersome for
some applications and produces large numbers of unused entries in mount tables. With the Automounter
filesystems need not be mounted until they are accessed. This reduces the size of mount tables (and hence the
time to search them). A simple form of filesystem replication for read-only filesystems can also be achieved
with the Automounter, enabling the load of accesses to frequently-used system files to be shared between
several NFS servers.
