----------------------------------
Thanks. Was going to spend more time to investigate this issue but is glad a
fix is already there.

> When Mesos slave is within the container, the COMMAND health check from
> Marathon is invoked incorrectly.
> In such a scenario, the sandbox directory (instead of the
> launcher/health-check directory) is used. This result in an error with the
> container.
