    No, just that however the secid is determined (whether indirectly via
    specification of a directory or directly via specification of a secid),
    the ability of the daemon to control what secid gets used ought to be
    controlled. Or, alternatively, the ability of the daemon to enable
    caching in a given directory ought to be controlled.
