- UUID is unique when it comes to device node naming. e.g. multiple USB device plug in and out can generate different /dev/sda nodes.
- UUID have been used by ubuntu by default to assign partition or hard disk in /etc/fstab.
- UUID have 25616 of combination and it takes a very long time to exhaust it even though if we were to generate it fast enough. e.g. generating 1 trillion a nano second would take 10 years to exhaust it.
- using UUID will list the partition or hard disk to appear in the 'File Browser' (aka Nautilus) under 'Places'.
This post will list 2 ways to get the UUIDs in order to make the new partition or hard disk automatically mount under Linux (or particularly Ubuntu), the command line and the GUI (Graphical User Interface) programs provided by Ubuntu.
