Universally Unique Identifier (UUID)

Ein valider UUID lässt sich unter Linux durch den Befehl uuidgen oder $ cat /proc/sys/kernel/random/uuid
erzeugen. Dem zweiten Dateisystem auf /dev/sdX kann dieser neue UUID zugeordnet werden:
$ tune2fs -U <UUID> /dev/sdX2
ifconfig eth0 | grep HWaddr | awk '{ print $NF}' | sed 's/://g'
$ uuidgen -r
$ uuidgen -t
$ blkdid $ blkid | grep UUID= $ ls -l /dev/disk/by-uuid $ lsblk -f $ lsblk -f | grep -v loop
Create a hash based on the UUIDs of your hard drive(s) instead:
$ blkid | grep -oP 'UUID="\K[^"]+' | sha256sum | awk '{print $1}'
