It's easier to manage a configuration through environment variables than through a config file if that config file has static values that need to change each version (such as the ES_CLASSPATH). Trying to keep that in Chef is tedious whereas just controlling these few settings with environment variables like most of the other settings in here is simple and straightforward.
