It's reasonably common to have UEFI systems that do not provide 
EFI_DEVICE_PATH_TO_TEXT_PROTOCOL, which is why efi_devpath_text() is 
used only in DBG() statements.

How is this feature expected to behave (both in terms of drive ordering 
and in terms of efimap output) if the protocol is not available?

Thanks,

Michael
