SystemD

SystemD is a system that is designed for the Linux Kernel.

SystemD is a suite of basic building blocks for a Linux system. As it replaces the sysvinit process to become the first process, that runs as PID1 and starts the rest of the system.

SystemD provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic.

SystemD also includes a logging daemon, utilities to control basic system configuration like the hostname, data, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.

SystemD provides support for automatically reverting to the previous version of the OS or kernel in case the system consistently fails to boot.
