The new code to lowercase all UUIDs is breaking NTFS mounts because those have UPPERcase UUIDs exclusivly. The correct fix would be to make blkid handle this as it knows what range of values the various UUIDs have and whether upper/lower casing them is even safe.

For initramfs-tools it is clear we should be checking that the UUIDs unmodified before attempting to change their case. This guearentees existing installs are never affected. We should likely also only case map those in a known UUID format which is case insensitive.
