> Containers launched with Unified Containerizer do not include container-specific CGroup FS mounts under {{/sys/fs/cgroup}}, which are created by default by Docker (usually readonly for unprivileged containers). Let's honor the same convention for Mesos containers.
> For example, this is needed by Uber's [{{automaxprocs}}|https://github.com/uber-go/automaxprocs] patch for Go programs, which amends {{GOMAXPROCS}} per CPU quota and requires access to the CPU cgroup subsystem.
