    For that one needs to know how the namespaces are used, not just how
    they are implemented. There was a long discussion on this on #kernel
    yesterday, by the way.

    Do they? In order for that to be a "clearly", I believe one needs to
    understand how namespaces are used in practice. It may not be desirable
    or even possible; this starts getting into a policy decision.

    I am not entirely sure what you mean with this, but it sounds incredibly
    dangerous to me.
