<p class="MsoNormal">I have a simple example of a service unit and bash script on rhel7 using Type=notify that I was trying to get working. When the service unit is configured to start the script as root things work as expected. When adding User=testuser
it fails. While the script initially starts (as seen on process list), Journalct -xe reports many lines like the following and the service eventually timesout. I am not even clear what these referenced PIDs are associated with as they don’t exist in the
process list.<o:p></o:p></p>
