SystemV Startup Versus Systemd

The new systemd daemon replaces the init process for some distributions already and is coming to many more. systemd provides service management and much more as well as startup for services designated to run on startup. It is designed to increase startup speeds as well as to conserve system resources by using a new startup strategy in which services are not started until they are actually required. This presentation will briefly review the Linux boot process and the old SystemV startup process. It will then discuss in more detail the startup process using systemd, and the reasons for creating the new systemd daemon and some of the advantages it provides. We will also discuss configuration files and some of the more common commands required to cause systemd to do our bidding. Backward compatibility will also be covered.
