Name : systemd Product : Fedora 34 Version : 248.5 Release : 1.fc34 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 daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.
This package was built from the 248.5-stable branch of systemd.
