According to 'man fstab' you can specify a device with LABEL=<label>, as long as you have set up a filesystem label with e.g. mkfs, or tune2fs. So, your "LABEL=boot" is correct. UUID on the other hand is meant to be specified like so: UUID=<uuid> In your case it would be: UUID=d32946b3-2236-4998-80dd-68b7d78e0c7b instead of it being preceded by "root=".
