How do I revert the manifold feature from an ISO?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The so called manifold feature Grml ISOs use by default allows one to use the same
-ISO for CD boot and USB boot. If you notice any problems when booting just

+The so-called manifold feature Grml ISOs can, but by default do not, use allows

% 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:
+syslinux, used by default for official Grml images) then just execute:
% isohybrid grml.iso
# boot the CD using normal el torito mode or copy it to USB device
# *without* having to run grml2usb (like: 'dd if=grml.iso of=/dev/sdX')
# - working both with the same ISO
+# Note that the manifold method is currently not be compatible with UEFI
+# setups.
# HYBRID_METHOD='disable' # do not create a hybrid ISO
-# HYBRID_METHOD='isohybrid' # use isohybrid from SYSLINUX
+# HYBRID_METHOD='isohybrid' # use isohybrid from SYSLINUX (default)
# HYBRID_METHOD='grub2' # use manifold with GRUB 2
-# HYBRID_METHOD='manifold' # use manifold with ISOLINUX (default)
+# HYBRID_METHOD='manifold' # use manifold with ISOLINUX
# Secure Boot method that should be used (amd64 only).
# If unset defaults to "disabled" (which means no Secure Boot will be present)
