Systemd-boot
Gummiboot is an open source boot loader for systems using the Unified Extensible Firmware Interface. 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 systems, 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.[1]
Gummiboot is licensed under the GNU Lesser General Public License version 2.1, unlike GRUB which is licensed under the GNU General Public License version 3. This distinction is intended to allow Gummiboot to be suitable for use on UEFI systems implementing "secure boot",[1] due to concerns surrounding the requirement of disclosure for the keys used to secure a system if software licensed under this version of the GPL are incorporated on a device that is locked using digital certificates.[2]
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.[2][1]
