Name        : systemd
Product     : Fedora 30
Version     : 241
Release     : 8.git9ef65cb.fc30
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 241-stable branch of systemd,
commit https://github.com/systemd/systemd-stable/commit/9ef65cb.

Update Information:

- Fix hang in flush_accept (#1702358) - Fix handling of RUN keys in udevd - Some
documentation and minor logging fixes - Backport the addition of
RestrictSUIDSGID= from systemd-242 and enable   RestrictSUIDSGID=yes for systemd
services which use DynamicUser=yes   (#1703356, CVE-2019-3843).   The defaults
in v242 were changed to enable RestrictSUIDSGID=yes if   DynamicUser=yes is
specified, but this backport doesn't do this and   RestrictSUIDSGID=yes has to
be requested explicitly. Maintainers of   other services packages for Fedora
should consider doing this.  No need to log out or reboot.
