25 * DbusPassiveRedundancy monitors the fan redundancy interface via dbus match
26 * for changes. When the "Status" property changes to Failed, all sensors in
27 * the interface's "Collection" property are added to the failed member. This
28 * set can then be queried by a sensor to see if they are part of a failed
29 * redundancy collection. When this happens, they get marked as failed.
