Artikel yang lumayan membantu untuk mempelajari systemd:

systemd is a suite of system management daemons, libraries, and utilities designed as a central management and configuration platform for the Linux computer operating system. Described by its authors as a “basic building block” for an operating system, systemd primarily aims to replace the Linux init system (the first process executed in user space during the Linux startup process) inherited from UNIX System V and Berkeley Software Distribution (BSD). The name systemd adheres to the Unix convention of making daemons easier to distinguish by having the letter d as the last letter of the filename.
