Purpose. The goal of autofs is to provide on-demand mounting and race free automatic unmounting of various other filesystems. This provides two key advantages: There is no need to delay boot until all filesystems that might be needed are mounted.
How do you automount in Need for Speed?
Use the following procedure to automatically mount an NFS share on Linux systems:
- Set up a mount point for the remote NFS share: sudo mkdir /var/backups.
- Open the /etc/fstab file with your text editor : sudo nano /etc/fstab.
- Run the mount command in one of the following forms to mount the NFS share:
What is the purpose of autofs?
Autofs is a kernel file system that supports automatic mounting and unmounting. When a request is made to access a file system at an autofs mount point, the following occurs: Autofs intercepts the request. Autofs sends a message to the automountd for the requested file system to be mounted.
What is NFS in Linux?
Network File Sharing (NFS) is a protocol that allows you to share directories and files with other Linux clients over a network. Shared directories are typically created on a file server, running the NFS server component. Users add files to them, which are then shared with other users who have access to the folder.

What is NFS and its purpose?
NFS is a low-cost solution for network file sharing that is easy to setup as it uses the existing IP infrastructure. A significant advantage of NFS is that it allows for central management, decreasing the need for added software and disk space on individual user systems.
How does NFS mount work?
NFS allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.
What does NFS provide in Linux?
Network File System (NFS) is one of the native ways of sharing files and applications across the network in the Linux/UNIX world. NFS is somewhat similar to Microsoft Windows File Sharing, in that it allows you to attach to a remote file system (or disk) and work with it as if it were a local drive-a handy tool for sharing files and large storage space among users.
