Сервис rsyslog не запускается из-под systemd с диагностикой:

=======================
Nov 27 17:32:47 bras-lpk.localdomain systemd[1]: syslog.socket: Socket service syslog.service not loaded, refusing.
Nov 27 17:32:47 bras-lpk.localdomain systemd[1]: Failed to listen on Syslog Socket.
Nov 27 17:32:47 bras-lpk.localdomain systemd[1]: Dependency failed for System Logging Service.
Nov 27 17:32:47 bras-lpk.localdomain systemd[1]: rsyslog.service: Job rsyslog.service/start failed with result 'dependency'.
======================

Поправил /lib/systemd/system/rsyslog.service.d/classic.conf в соотвествии с: https://lists.freedesktop.org/archives/systemd-devel/2015-February/027988.html

-Requires=syslog.socket
+After=syslog.socket

И сервис начал запускаться при старте системы нормально.

$ rpm -qa| grep rsyslog| sort
rsyslog-8.16.0-alt3
rsyslog-classic-8.16.0-alt3
