-  * Some updates in config_time(), thanks to Thomas Lehmann:
+  [ Michael Prokop ]
+  * Some updates in config_time(), *many* thanks to Thomas Lehmann:
+    - improve localtime / utc / gmt handling
     - use UTC="--localtime" by default
     - evaluate tz bootoption in this function as well
     - execute hwclock even if /dev/rtc isn't available, just display
       warning regarding the lack of /dev/rtc
+  [ Ulrich Dangel ]
+  * Refactored config unpacking config parameter will now be honored,
+    e.g. config=foo.tbz myconfig=/dev/sda1 is now possible.
+  * Get always the right boot parameter via /proc/cmdline.
+    [Testing: issue520]
