As an aside, it is actually an error to describe this as a "loopback" device, because that is incorrect. It is a "loop" device [1]. The word "loopback" does not appear in 'man mount'. A *loop* device is a filesystem technique to make a file accessible as a block device. A *loopback* device is a virtual network interface.
