+grml2usb fails with "Fatal: file default.cfg could not be found."
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are trying to install an older grml ISO (older than grml 2009.10) with a
+recent version of grml2usb then you might notice:
+
+ Fatal: file default.cfg could not be found.
+ Note: this grml2usb version requires an ISO generated by grml-live >=0.9.24 ...
+ ... either use grml releases >=2009.10 or switch to an older grml2usb version.
+ Please visit http://grml.org/grml2usb/#grml2usb-compat for further information
+ Fatal: a critical error happend during execution (not a grml ISO?), giving up
+
+Breaking the backward compatibility was necessary to avoid maintainability hell.
+If you want to install older grml ISOs please grab the grml2usb-compat Debian
+package which provides support for older releases or the
