Description:
system and service manager
systemd is a system and service manager for Linux. It 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 is compatible with SysV and LSB init scripts and can work as a drop-in replacement for sysvinit. . Installing the systemd package will not switch your init system unless you boot with init=/bin/systemd or install systemd-sysv in addition.
