At times we may need to debug systemd if we dont know what is going on or especially if some command is running via systemd but we dont know which unit/service is responsible for running this command. In such cases enable debug option in systemd using:

1. Edit '/etc/systemd/system.conf' and set:

   LogLevel=debug

2. Reload systemd for changes to take effect:

   systemctl deamon-reload

3. Then logs should come to /var/log/messages for additional debugging.
