Managing system services with systemd
In this section, you will learn how to manage system services, runtime targets, and all about the service status with systemd. You will also learn how to manage system boot targets and services that should start at system boot.
systemd (which you can learn a bit about at https://www.freedesktop.org/wiki/Software/systemd/) is defined as a system daemon that’s used to manage the system. It came as a rework of how a system boots and starts, and it looks at the limitations related to the traditional way of doing it.
