Comment # 1 on bug 1110456 from Thorsten Kukuk

simple test: "logger aaa"

On openSUSE Kubic (current Factory) we use the same setup as with SLES:
journald and rsyslog. On openSUSE Kubic the string "aaa" is only visible in
journalctl, not in /var/log/messages. As result, this log entry is gone after a
reboot. Which is critical for us, as it does not allow us to debug problems.

On SLES15, "aaa" is visible in journalctl and /var/log/messages.
