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 and running

containers and virtual machines, system accounts, runtime directories

and settings, and daemons to manage simple network configuration,

network time synchronization, log forwarding, and name resolution.

- systemd-detect-virt QEMU CPUID logic update - Fix cryptsetup devices

disappearing when used for btrfs - Fix rfkill on some thinkpads - Extend dbus

timeouts to handle slow dbus daemon startup - Fix systemd-resolved DOS with

crafted NSEC packets (LP#1725351) - Backport /etc/crypttab _netdev feature from

upstream - Update hwdb (No need to reboot.)

su -c 'dnf upgrade systemd' at the command line.
