31 * On the first application launch, the configuration update thread that application spawns, has no chance to run yet
32 * and prepare initial application configuration. In this case, it needs to be fetched from outside of the application,
33 * so this is run from the .sh script.
34 * Later on, once application is already started it will take care of the configuration update itself
