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.
 .
 This package provides the manual pages and links needed for systemd
 to replace sysvinit. Installing systemd-sysv will overwrite /sbin/init with a
 link to systemd.
