As Carsten says the problem is not just extracting files, if for example you want to create a Docker image that will startup quickly it's best to wait until the application is ready before considering the image fully built. My suggestion is to add a command-line option as you suggest, and make the logic that decides when to exit configurable. That can simply be a combination of StartupListener and health checks, where a configuration says "consider this instance ready when N health checks tagged with 'startup' pass" for example. That would be a generally useful addition IMO. Having to configure N is not ideal but I'm not sure how you can guarantee that all required health checks are present otherwise. -Bertrand
