--------------------------------------------------------
{{modprobe -q overlay}} and check exit status sound reasonable to me.
Since this doesn't apply to all filesystems, we can do it in
{{OverlayBackend::create(const Flags&)}} and keep {{Try<bool> supported(const
std::string& fsname);}} unchanged.

> URL: https://issues.apache.org/jira/browse/MESOS-4969
> Project: Mesos
> Issue Type: Bug
> Components: isolation, volumes
> Reporter: James Peach
> Priority: Minor
>
> On my Fedora 23, overlayfs is a module that is not loaded by default
> (attempting to mount an overlayfs automatically triggers the module loading).
> However {{mesos-slave}} won't start until I manually load the module since it
> is not listed in {{/proc/filesystems}} until is it loaded.
> It would be nice if there was a more reliable way to determine overlayfs
> support.
