Name : systemd
Product : Fedora 36
Version : 250.9
Release : 1.fc36
URL :   https://www.freedesktop.org/wiki/Software/systemd
Summary : System and Service Manager
Description :
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 250.9-stable branch of systemd.
