Ilya Pronin commented on MESOS-7034:
------------------------------------

It doesn't feel 100% right with me either. But "overlay" doesn't have any parameters so the only concern will be when it is loaded.

Also looks like Docker does the same thing though in their docs they tell that the module should already be loaded: https://github.com/docker/docker/blob/master/daemon/graphdriver/overlay2/overlay.go#L224

> Mesos agent reads {{/proc/filesystems}} to check is a filesystem is supported. However for optional filesystems such as {{overlayfs}}, the modules are not loaded by default. Hence attempt to run a {{modprobe overlayfs}} command before reading the {{/proc/filesystems}} file.
