Specify the CLASSES to be used for building the ISO via FAI. By default only
the classes GRMLBASE, GRML_FULL and I386/AMD64 (depending on system

-appropriate architecture as well. Additionally you can specify a class providing

How do I revert the manifold feature from an ISO?

First of all create the chroot using debootstrap (requires root):
BASECHROOT='/tmp/basefile' # path where the chroot gets generated
- SUITE='jessie' # using the current stable release should always work
+ SUITE='stretch' # using the current stable release should always work
debootstrap --exclude=info,tasksel,tasksel-data "$SUITE" "$BASECHROOT" http://ftp.debian.org/debian
tar -C "$BASECHROOT" --exclude='var/cache/apt/archives/*.deb' -zcf "${SUITE}".tar.gz ./
# export GRML_FAI_CONFIG=$(pwd)/etc/grml/fai
# export SCRIPTS_DIRECTORY=$(pwd)/scripts
+ # export TEMPLATE_DIRECTORY=$(pwd)/templates
# ./grml-live -s sid -a amd64 -c GRMLBASE,GRML_FULL,AMD64
