At the time when I did this there was no syslog-ng.service in
/usr/lib/systemd/system, now there is, but my unit file is like this:
[Unit]
Description=System Logger Daemon
Documentation=man:syslog-ng(8)
[Service]
Sockets=syslog.socket
ExecStart=/usr/sbin/syslog-ng -F
ExecReload=/bin/kill -HUP $MAINPID
#Restart=on-failure
[Install]
WantedBy=multi-user.target
Alias=syslog.service
Is there a reason why this should not work?
