Why are you building your own rpm? Elasticsearch [provides an rpm](https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html). ---

A few things have changed in the startup scripts over those versions. I'm not sure what exactly, but the rpm is setup with the correct paths for bin/elasticsearch to know how to start as a service. ---
