What is Systemd?
Systemd is a Linux software suite that provides a set of system tools that behave consistently across distributions of the operating system. It gets its name from "System D," which is a concept coined by Anthony Bourdain that refers to the ability to quickly adapt in order to solve problems.
The chief component of systemd is init, which is a process that bootstraps user space and manages user processes. Systemd also provides a set of daemons and utilities that offer device management, login management, network connection management and event logging.
In recent years, systemd has supplanted similar tools, such as System V (SysV) and BSD init.
You configure systemd using a plain-text configuration file known as a unit file. These files use a declarative language that have replaced the per-daemon startup shell scripts that were once common.
Systemd is available for all major Linux distributions. But it is not enabled by default on all of them.
