I see the following code in
https://github.com/kubernetes/kubernetes/blob/v1.2.4/pkg/api/types.go#L150:
// NamespaceSystem is the system namespace where we place *system
components*.
NamespaceSystem string = "kube-system"
So the purpose of this namespace is to place system components. But I am
not sure what are the system components, are kube-dns, dashboard and other
add-ons system components?
