Swapping a drive between machines means that you now have a drive UUID 
that doesn't match any of the boot options. 3.3 says that it should then 
attempt to boot from the device, and the only spec-defined boot location 
is EFI/BOOT/BOOT(machine type).efi. It seems to conform to the spec 
perfectly.
