'''systemd-boot''', formerly known as '''gummiboot''', is a [[Free and open-source software|free and open-source]] [[Bootloader|boot manager]] created by obsoleting '''gummiboot''' project and merging it into [[systemd]] in May 2015.<ref>{{cite web | url = http://www.rodsbooks.com/efi-bootloaders/gummiboot.html| title = Managing EFI Boot Loaders for Linux: Using gummiboot| author = Rod Smith| date = 2013-04-27}}</ref> It was created when gummiboot was merged into [[systemd]] and renamed to "systemd-boot" in May 2015.<ref>{{cite web| url = https://www.phoronix.com/scan.php?page=news_item&px=Systemd-220| title = Systemd 220 Has Finally Been Released | date = 2015-05-21 | accessdate = 2015-08-17 | author = Michael Larabel | publisher = [[Phoronix]]}}</ref><ref>{{cite web | url = http://lists.freedesktop.org/archives/systemd-devel/2015-May/032147.html | title = <nowiki>[systemd-devel] [ANNOUNCE]</nowiki> systemd&nbsp;v220 | date = 2015-05-21 | accessdate = 2021-09-27 | author = [[Lennart Poettering]] | website = lists.freedesktop.org}}</ref><ref>{{cite web | url = https://phoronix.com/scan.php?page=news_item&px=Gummiboot-Is-Dead | title = Gummiboot is Dead | date = 2015-07-07 | accessdate = 2015-08-17 | author = Michael Larabel | publisher = [[Phoronix]]}}</ref>

DesignedGummiboot for systems using the [[Unified Extensible Firmware Interface]] (UEFI) andwas developed by the [[Red Hat]] employees [[Kay Sievers]] and [[Harald Hoyer]], gummibootand was intended todesigned beas a minimal alternative to [[GNU GRUB]] thatfor "justsystems works",using itthe [[Unified Extensible Firmware Interface]] (UEFI). It automatically detected bootable images (including [[Linux kernel]] images, [[operating system]]s, 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.<ref>{{Cite web|url=https://systemd.io/BOOT_LOADER_INTERFACE/|title = Boot Loader Interface}}</ref>

As a [[word play]], the name "gummiboot" means "[[inflatable boat|rubber (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]] did not use gummiboot for booting UEFI systems; instead, it used efilinux to [[chainload]] GRUB.<ref name="theh-gummi" /><ref name="lwn-efilinux" />

gummiboot was 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 was intended to allow gummiboot to be suitable for use on UEFI systems implementing "[[Secure Boot|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>
