*Choosing a quota:* Most deployments will want a quota that's at least 10G. From there, a larger quota can help reduce compute overhead by preventing reloading the same Docker image repeatedly, but will leave less space for other files on the same storage (usually Docker volumes). Make sure the quota is less than the total space available for Docker images.
-*On Debian-based systems,* the @arvados-docker-cleaner@ service is enabled automatically when installed. Restart the service after updating the configuration file:
