My First Post on my blog
One drawback to using /etc/fstab is that, regardless of how infrequently a user accesses the NFS mounted filesystem, 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 many systems at one time, overall system performance can be affected. An alternative to /etc/fstab is to use the kernel-based automount utility. An automounter consists of two components:
The automount utility can mount and unmount NFS file systems automatically (on-demand mounting), therefore saving system resources. It can be used to mount other file systems including AFS, SMBFS, CIFS, and local filesystems.

- a kernel module that implements a file system, and
- a user-space daemon that performs all of the other functions.
