    [PATCH] Cleanup: the initialization method is operated if it is possible.
    
    On current code, the initialization method is operated only if
    the method is necessary. That is not wrong, but that is a little
    complex because makedumpfile has many options and there are many
    situations the method is necessary or unnecessary.
    So the initialization method is operated always if it is possible.
