title: Is it possible to deploy a pharo image without .changes and .sources files
body: <p>I've built a pharo application that I want to give to my customers. The application is based on seaside and will run headless. For this I don't need the .source and .changes file. I would like to save some space in the distribution archive and therefor I'd like to skip those files.</p>
  
  <p>At the moment it appears to me that pharo is complaining anyway if those files are missing. Is there a chance to start the image without .sources and .changes file?</p>
