When built with `D=1` chreipl-fcp-mpath automatically creates debug data for the helpers that run during udev event processing. This is the only way to effectively debug what is happening during event processing in chreipl-fcp-mpath. Collect this data under its default path in /run/udev/. Also collect the chreipl-fcp-mpath statefile which contains WWID, Device Bus-ID and LUN of the last path that was detected to represent a FCP re-IPL device.
