+Ramdisk support for applying HP iLO firmware.
+
+The firmware files are copied in via an extra-data hook: the variable
+DIB\_ILO\_FIRMWARE\_PATH specifies a directory, and every file in that directory
+will be unpacked into a same-named directory in the ramdisk (using
+--unpack=...). If the path is not specified, a diagnostic is output but no
+error is triggered.
+
+During ramdisk init every found firmware installer will be executed using
+--silent --log=log The log is displayed after the firmware has executed.
+
+If the firmware exits with status 0 (ok), status 2 (same or older version) or 4
+(ilo not detected) a diagnostic message is logged and init proceeds.
+
+Any other status code is treated as an error.
