The init script that invokes install and install-efi scripts passes the first parameter that identifies the boot drive but in cases when this disk is labeled and kernel configurations allow disk labeling under /run/media/ this would pass the disk label. The earlier implementation considered that the drive name will be passed and in case the label is passed it fails and provides the boot drive as an option for installation driver. We now use a more generic approach to identify the boot drive which can handle both drive name as well as label if passed.
