Designed for systems using the [[Unified Extensible Firmware Interface]] (UEFI) and developed by the [[Red Hat]] employees [[Kay Sievers]] and [[Harald Hoyer]], gummiboot iswas intended to be a minimal alternative to [[GNU GRUB]] that "just works": it automatically detectsdetected bootable images (including [[Linux kernel]] images, [[operating system]]s, and other boot loaders), doesdid not require a configuration file, providesprovided a basic menu-based interface, and cancould also integrate with systemd to provide performance data.<ref>https://systemd.io/BOOT_LOADER_INTERFACE/</ref>
As a [[word play]], the name "gummiboot" means "[[inflatable boat]]" in [[German language|German]], the native language of its initial developers.<ref name="theh-gummi" /> Despite being developed by two of its employees, Red Hat's [[Fedora (operating system)|Fedora Project]] doesdid not use gummiboot for booting UEFI systems; instead, it will useused efilinux to [[chainload]] GRUB.<ref name="theh-gummi" /><ref name="lwn-efilinux" />
gummiboot iswas licensed under [[GNU Lesser General Public License|LGPL-2.1-or-later]], unlike GRUB which is licensed under the [[GNU General Public License|GPL-3.0-or-later]]. This distinction iswas intended to allow gummiboot to be suitable for use on UEFI systems implementing "secure boot",<ref name=theh-gummi>{{cite web|title=Gummiboot is an EFI boot loader that "just works"|url=http://www.h-online.com/open/news/item/Gummiboot-is-an-EFI-boot-loader-that-just-works-1628719.html|publisher=The H|accessdate=11 September 2012}}</ref> due to concerns surrounding its requirement to distribute all authorization keys ([[digital certificate]]s) needed to run GPL-v3-licensed software if [[hardware restrictions]] such as secure boot are in effect.<ref name=lwn-efilinux>{{cite web|title=Ubuntu details its UEFI secure boot plans|url=https://lwn.net/Articles/503803/|publisher=Linux Weekly News|accessdate=11 September 2012}}</ref>
