autofs

One drawback to using
NFS mounted file system, the system must dedicate resources to keep the mounted file system
in place. This is not a problem with one or two mounts, but when the system is maintaining
mounts to a dozen systems at one time, overall system performance can suffer. An alternative
to is to use the kernel-based
/etc/fstab
file systems automatically, saving resources.
The service is used to control the
autofs
primary configuration file. While
convenient to specify the mount points, hostname, exported directory, and options in a set of
files rather than typing them manually.
The configuration files are arranged in a parent-child relationship. The main
