gummiboot (software)

gummiboot is an open-source boot manager[2]. Its final independent release is version 48. It has since been merged into systemd as its systemd-boot component and maintained as such.[3][4][5]

Designed for systems using the Unified Extensible Firmware Interface (UEFI) and developed by the Red Hat employees Kay Sievers and Harald Hoyer, gummiboot is intended to be a minimal alternative to GNU GRUB that "just works": it automatically detects bootable images (including Linux kernel images, operating systems, and other boot loaders), does not require a configuration file, provides a basic menu-based interface, and can also integrate with systemd to provide performance data.

As a word play, the name "gummiboot" means "inflatable boat" in German, the native language of its initial developers.[6] Despite being developed by two of its employees, Red Hat's Fedora Project does not use gummiboot for booting UEFI systems; instead, it will use efilinux to chainload GRUB.[6][7]

gummiboot is licensed under version 2.1 of the GNU Lesser General Public License, unlike GRUB which is licensed under the GNU General Public License version 3 (GPL v3). This distinction is intended to allow gummiboot to be suitable for use on UEFI systems implementing "secure boot",[6] due to concerns surrounding its requirement to distribute all authorization keys (digital certificates) needed to run GPL-v3-licensed software if hardware restrictions such as secure boot are in effect.[7]
