Has anyone ever cloned a disk with GPT? - PLG Social

So, I’m trying to clone an SSD to an NVME drive and I’m bumping into this “dev-disk-by” error when I boot from the NVME (the SSD is unplugged). I can’t find anyone talking about this in this context. It seems like what I’ve done here should be fine and should work, but there’s clearly something I and the arch wiki are missing.

probably the disk UUID has changed because of the path to the NVMe vs SSD. If you use partition UUID, they will be exactly the same, but the UUID of the physical disk is not cloned, as it is a identifier of the physical device and not it’s content.

change it to partition UUID and it will boot.

So I fixed this by using clonezilla (which seemed to fix things up automatically), but for my edification, how do you get the UUID of the device itself? The only UUIDs I was seeing seemingly were the partition UUIDs.
