systemd System and Service Manager
What is this?
systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts.
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, supports snapshotting and restoring of the system state, maintains mount and
automount points and implements an elaborate transactional dependency-based service control logic.
