The final step after formatting a partition is to mount the partition. We use the mount command to mount a partition and the unmount command to unmount a partition. The mount command is also used for viewing the current mount points in our system. However, after a reboot, all partitions are unmounted, unless we created entries in the /etc/fstab directory.
You need a root privilege to save any change in the /etc/fstab. It's also important to back up any configuration file(s) before making any change(s).
