What is an FSTAB file?

FSTAB files mostly belong to mount. FSTAB file is a system configuration file associated with Unix, Linux and Unix-like operating systems. A typical FSTAB file specifies disk-partition, remote file system and other data sources, not necessarily disk based. These system configuration files define the order in which file systems are mounted during system's boot.

Main Usage: As mentioned earlier, FSTAB file lists file systems and each file system are described in a separate line. Each line consists of six fields of description. This defines how each file system and disk must be initialized and integrated into the system's file system.
Content in an FSTAB File: Earlier when mounting was done manually for each device connected to your system, the mount command had to read FSTAB file to know how and where the respective device must be mounted. Those devices could be CDs, DVDs or floppies. To make the process easier FSTAB file stores information like device name, mount point, file system type, and the partition archiving schedule etc. It also contains data to determine whether mounting of file system should be done at boot.
