Why I did it
"show reboot-cause history" does not report the latest reboot-cause because process-reboot-cause does not wait for determine-reboot-cause to complete running before it starts.
Currently the system just assumes that process-reboot-cause will run after determine-reboot-cause based on timing. This fix is fixing the race condition that might happen if the determine-reboot-cause does not finish before process-reboot-cause.
How I did it
This PR makes determine-reboot-cause.service into a oneshot service to ensure process-reboot-cause only runs once determine-reboot-cause completes.
This fix depends on a PR for process-reboot-cause.service dependency, which needs to be committed to 202205 branch.
#11213
How to verify it
Run "show reboot-cause" and "show reboot-cause history"
The latest entry in reboot-cause history should match the output of show reboot-cause.
Can check the journal logs of determine-reboot-cause.service and process-reboot-cause.service after a reboot to confirm that process-reboot-cause only runs after determine-reboot cause.
