I agree that this makes the development process a bit more complex at the moment, but I think that the way to make it simpler is not to continue adding things to standalone.conf. I think that we should move towards a development environment that is closer to the production environment, not the other way around.

Ideally the developer should be able to do something like "make install" to have the engine deployed to a directory structure similar to what he have in the production environment.

Then you should be able to go to the bin directory inside that structure and start the engine (and the other tools) using the same script that we use in production environments. If we achieve this goal then we have a simple development environment setup and also we have all developers testing almost the same thing that will go into the production environments.

At the moment we don't have that, most times you are testing something quite different (in terms of directory structure, configuration, etc) to what will be installed in production environments.
