It's subtle, but that's probably why the parameter is called
GRUB_DISABLE_LINUX_UUID and not GRUB_DISABLE_UUID.

>From the docs:

'GRUB_DISABLE_LINUX_UUID'
     Normally, 'grub-mkconfig' will generate menu entries that use
     universally-unique identifiers (UUIDs) to identify the root
     filesystem to the Linux kernel, using a 'root=UUID=...' kernel
     parameter.  This is usually more reliable, but in some cases it may
     not be appropriate.  To disable the use of UUIDs, set this option
     to 'true'.

Cheers,
