+What is $GRML_FAI_CONFIG?
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The variable '$GRML_FAI_CONFIG' is pointing to the directory /etc/grml/fai by
+default. To provide you a maximum of flexibility you can set up your own
+configuration directory (e.g. based on /etc/grml/fai) and use this directory
+running grml-live with the '-D <config_dir>' option. Now '$GRML_FAI_CONFIG'
+points to the specified directory instead of using /etc/grml/fai and all the
+configuration files, scripts and hooks will be taken from your
+'$GRML_FAI_CONFIG' directory.
