[AL2] Author-Standby promotion process failed to start AEM Author Service about aem-aws-stack-builder HOT 3 OPEN

The root cause of this failing is because we are managing the state of AEM via the old service & the newsystemctl command.

During provisioning AEM gets started with the systemctl command. The author standby promotion uses the service command for stopping & starting AEM.

During the service stop service aem-author stop, the cq.pid PID file gets deleted. During service start service aem-author-start the service script triggers a stop via systemctl, to ensure that there is no other service running. This stopping via systemctl fails because the stop script tries to delete the cq.pid file. Since it doesn't exist anymore the stop via systemctl is failing and therefore the start via service fails.

The solution is to make sure that all service commands are replaced with the systemd command systemctl.

AEM AWS Stack Provisioner 6.4.0 includes the replacement of all service commands with systemctl.

The next step is to replace the service command with systemctl in the manage service SSM Command, to make sure that the author standby promotion works even after an offline snapshot was taken.
