(1) During installation we add empty value mappings: "APC Battery Replacement Status", "APC Battery Status", "Dell Open Manage System Status", "HP Insight System Status".
(2) We cannot "Save" an empty value mapping. This means that had we wanted to change, e.g., name of "APC Battery Replacement Status", it would not be possible to do it. Then again, if we solve (1), then we probably do not need to worry about (2).
