+ * Improve check for architecture which should be build: if not specified
+ assume a safe default and check this one.
+ * Unify variable default checks, always assume sane defaults.
+ * Always run $SUITE checks, so grml-live repository is used also
+ if suite isn't manually specified.
+ * New graphical boot menu. Can be disabled via ISOLINUX_METHOD=console.
+ * New configuration variables DISTRI_NAME and DISTRI_INFO which should allow
+ easier rebranding of grml-live based distributions.
+ * Detect existence of stage 'boot' using boot/isolinux so grml-live
+ executed with options '-q -B' and empty boot/isolinux works as well.
