Summary

systemd is a system and service manager that runs as PID 1 and starts the rest

of the system. 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 supports SysV and LSB init scripts and works as a

replacement for sysvinit. Other parts of this package are a logging daemon,

utilities to control basic system configuration like the hostname, date, locale,

maintain a list of logged-in users, system accounts, runtime directories and

settings, and a logging daemons.

This package was built from the v259-stable branch of systemd.
