fstab (filesystem table) is a configuration file commonly found at /etc/fstab on Linux and Unix-like systems. This is commonly provided by the util-linux package and maintained by the systems administrator.
fstab lists available data sources such as disk partitions, removable media, or networked resources such as NFS or SMB shares.
fstab is read by the mount command at boot time and by subsequent calls after the machine has booted in order to apply each mount point as intended by the system.
