- No separation of trusted/untrusted builders
- docker-worker/generic-worker specific scripts should not be run on all builders
- No process to install docker-worker yet

- Consolidate shell script variables to a globals / variables file where it makes sense
- Template builders via jinja2 to support arbitrary combinations of scripts
- Windows?
