        Note that if a node is unreachable at the time a hooks is run,

        this will not be interpreted as a deny for the execution. In

        other words, only an actual error returned from a script will

        cause abort, and not an unreachable node.

        Therefore, if you want to guarantee that a hook script is run

        and denies an action, it's best to put it on the master node.
