<pre>systemctl would fail to start syslog-ng.service with the following journal

...
In spite of the line "ExecStart=/usr/sbin/syslog-ng -F" in syslog-ng.service
file, the journal line "About to execute /usr/sbin/syslog-ng -n" implies it was
ignoring the "-F" flag.
The syslog-ng daemon doesn't support the "-n" flag (at least not version
<span class="quote">>=3.4.1). "/usr/sbin/syslog-ng -n; echo $?" returns 1, corresponding to the</span >
journal output "code=exited, status=1/FAILURE".
To test if this was the problem, I altered the gprocess.c file in the syslog-ng
source to accept "-n", instead of "-F", to enable foregrounding.
After recompiling and installing, syslog-ng.service started and remained active
without a problem.
The journal output is:
...
