This allows this container to start up before X is ready on the main container and restart the process until it becomes available.
Each restart will have a small delay of a few seconds. So 50 attempts should be a few mins.
This requires that you still have setup a primary container instance of this image.
We can then run a secondary instance of steam that will use the existing X server.
We are still limited to running one of these steam instances at a time.
The current supervisor.d configs are configured specifically for a particular supervisor version / installation.
This decouples the configuration so we can use it on any distro.
