systemd-boot is a free and open-source boot manager created by obsoleting the gummiboot project and merging it into systemd in May 2015. [1] [2] [3] [4]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).
systemd-analyze may be used to determine system boot-up performance statistics and retrieve other state and tracing information from the system and service manager. systemd tracks processes using the Linux kernel's cgroups subsystem instead of using process identifiers (PIDs); thus, daemons cannot "escape" systemd, not even by double-forking.
Like init, systemd is a daemon that manages other daemons. All daemons, including systemd, are background processes. Lennart Poettering and Kay Sievers, software engineers that initially developed systemd, [23] sought to surpass the efficiency of the init daemon in several ways.

GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
Arch Linux (/ ɑːr tʃ /) [7] [8] [f] is an open source, rolling release Linux distribution. Arch Linux is kept up-to-date by regularly updating the individual pieces of software that it comprises. [9] Arch Linux is intentionally minimal, and is meant to be configured by the user during installation so they may add only what they require. [10]
A bootloader, for example GNU GRUB, LILO, SYSLINUX or systemd-boot. This is a program that loads the Linux kernel into the computer's main memory, by being executed by the computer when it is turned on and after the firmware initialization is performed. An init program, such as the traditional sysvinit and the newer systemd, OpenRC and Upstart.
