Tutorial: An Introduction to Managing a Linux Server with systemd
Filed under: Technical Support
What is systemd?

Systemd is the System Management Daemon, which provides a standard for controlling the Linux boot process. It is named per the UNIX convention of adding ‘d’ to the end of daemon’s name. Systemd is intended as a drop-in replacement for the very common init start-up scripts for the boot process (which is also referred to as System V or SysV).
