Using UUID to identify you partitions is better then using kernel device names .i.e /dev/sd?. Mainly on systems where drives get move around frequently. Dev names change when the physical order of the drives are change but the UUID always remains the same.
You can use the “lsblk” or “blkid” command to get the UUID of your partitions. In this case I’m running it on my Arch Linux box.
