This update introduces a non-reboot patch example script for a service whose patch modified its service file thereby requiring a system daemon-reload as a precursor to the service process restart. This new RPM was introduced in support of no-reboot patching of the 'influxdb' and 'collectd' processes ; so those are the default processes used in this script. Note that there is nothing that prevents a designer from using this as a more general example script for any service that requires the same patching operations after replacing the default process names with their own.
