That image should:

• manage the Tomcat version in one place rather than 4
• define the convention on where light modules & content-importer data are expected, e.g. -Dmagnolia.content.bootstrap.dir
• define useful defaults such as:
  • -Dmagnolia.content.bootstrap.onlyImportAtInstall=true
  • -Dmagnolia.content.bootstrap.createTasks=never
  • -Dmagnolia.update.auto=true
• be on GitHub so the community can contribute feedback
