'''systemd-boot''' is a [[Free and open-source software|free and open-source]] [[Bootloader|boot manager]], previously known as '''gummiboot'''.

'''gummiboot''' is an [[open-source]] [[boot loader]] for systems using the [[Unified Extensible Firmware Interface]] (UEFI). Developed by the [[Red Hat]] employees [[Kay Sievers]] and [[Harald Hoyer]], it is intended to be a minimal alternative to [[GNU GRUB]] that "just works": it automatically detects bootable images (including [[Linux kernel]] images, [[operating system]]s, and other boot loaders), does not require a configuration file, provides a basic menu interface, and can also integrate with [[systemd]] to provide performance data. Its name, as a [[word play]], means [[inflatable boat]] in [[German language|German]], which is native language of the initial developers.<ref name="theh-gummi" />
