If you do without setting GRML_FAI_CONFIG, it will not use your edited FAI
scripts, but the ones installed by default.

+In case you want to run grml-live directly from the checkout (after
+making sure all dependencies are installed), you should set
+`GRML_FAI_CONFIG` so that it does not use the config files of an
+installed `grml-live` package:
+
+    # export GRML_FAI_CONFIG=$(pwd)/etc/grml/fai
+    # ./grml-live -s sid -a amd64 -c GRMLBASE,GRML_FULL,AMD64
