The new systemd-boot enabled in OE is the old gummiboot merged into systemd project. Our intention is to replace gummiboot with systemd-boot in OE once every feature based on gummiboot is supported with systemd-boot. Before we can purge gummiboot, we temporarily keep both of the two bootloaders supported. Patch doesn't do replacement for every "gummi" occurrence. We think cleaning can be done in background after we disable people to use gummiboot, so we just keep change small and safe this time.
