gummiboot was developed by the Red Hat employees Kay Sievers and Harald Hoyer and designed as a minimal alternative to GNU GRUB for systems using the Unified Extensible Firmware Interface (UEFI). It automatically detected bootable images (including operating systems and other boot loaders), did not require a configuration file, provided a basic menu-based interface, and could also integrate with systemd to provide performance data.[5]
As a word play, the name "gummiboot" means "rubber (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 did not use gummiboot for booting UEFI systems; instead, it used efilinux to chainload GRUB.[6][7]
gummiboot was licensed under LGPL-2.1-or-later, unlike GRUB which is licensed under the GPL-3.0-or-later. This distinction was 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]
