-Sure. Just adjust the variables GRML_LIVE_SOURCES and FAI_DEBOOTSTRAP (if not
-already using NFSROOT's base.tgz) inside /etc/grml/grml-live.conf according to
-your needs. Please don't forget that you should use the grml servers as well
-(see default configuration) so all the grml packages can be downloaded as well.
+Yes. Set up an according sources.list configuration as class file in
+${GRML_FAI_CONFIG}/config/files/etc/apt/sources.list.d/ and adjust the variable
+FAI_DEBOOTSTRAP (if not already using NFSROOT's base.tgz) inside
+/etc/grml/grml-live.conf[.local]. If you're setting up your own class file don't
+forget to include the class name in the class list (grml-live -c ...).
