A Universally Unique Identifier (UUID) is an identifier standard used in software construction whose intent is to enable distributed systems to uniquely identify information without significant central coordination.
Typically, a UUID consists of 32 hexadecimal digits, displayed in 5 groups separated by hyphens, e.g.:
To get a list of the UUIDs for your partitions:
- open a terminal window
- become root (type su and then enter your root password at the prompt)
- use the command blkid
