This to test in Atomic Image and Base Image.

How to test

  1. ssh into an instance.
  2. Next we will reboot the image.
 $ sudo reboot

3. Now we will find that PID of systemd-journald.

 $ systemctl show systemd-journald.service -p MainPID

4. Finally we will check whether journal gets written to disk or not.

  $ sudo ls -l /proc/<MainPID>/fd/ | grep journal
