+How do I revert the manifold feature from an ISO?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The so called manifold feature Grml ISOs use by default allows to use the same
+ISO for CD boot and USB boot. If you notice any problems when booting just
+revert the manifold feature running:
+
+ % dd if=/dev/zero of=grml.iso bs=512 count=1 conv=notrunc
+
+To switch from manifold to isohybrid mode (an alternative approach provided by
+syslinux) then just execute:
+
+ % isohybrid grml.iso

+How to I create a base tar.gz (I386.tar.gz or AMD64.tar.gz)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Execute the following commands (requires root):
+
+ ARCH='amd64' # replace with i386 if necessary
+ SUITE='squeeze' # using the current stable release should always work
+ debootstrap --arch "$ARCH" --exclude=info,tasksel,tasksel-data "$SUITE" "$ARCH" http://debian.netcologne.de/debian
+ cd "$ARCH"
+ rm var/cache/apt/archives/*.deb
+ tar zcf ../"${ARCH}".tar.gz *
+
+And finally place the generated tarball in /etc/grml/fai/config/basefiles/ (note
+that it needs to be uppercase letters matching the class names, so: AMD64.tar.gz
+for amd64 and I386.tar.gz for i386).
