In the Linux operating system, the disks are mounted through labels, instead of device path. This is the most effective approach as the device name and path may change when you boot and thus may create several complications for the system and hence for the user.

So the disks are assigned labels so that the devices may mount up in the correct place. Thus disk labels are the important structure for the access of the Linux volumes. All entries for disks to be mounted at startup are in the file /etc/fstab.
