any suggestions as how to mount a KNOPPIX iso as a chroot or how to make a Knoppix chroot?

1. Copy the Knoppix ISO to your hard drive.

2. mount -t iso9660 -o ro,loop /path/name.iso /ISO_mountpoint

3. chroot (somewhere appropriate within the mounted filesystem).

I haven't actually done this, but psychologists regularly counsel suicidal teenagers, and the psychologists haven't committed suicide, so what do they know?

Well, that suggestion might almost work. What I did was:

1) Install cloop utils to extract the Knoppix sytem from the ISO
aptitude install cloop-utils

mount -t iso9660 KNOPPIX_V6.0.1CD-2009-02-08-EN.iso /var/chroot/knoppix -o loop

There's more info here:

You'll need to compile the kernel module for cloop:

wget http://debian-knoppix.alioth.debian....2.629-1.tar.gz


tar -xvf cloop*
cd cloop-*

make KERNEL_DIR=/usr/src/linux-2.6.30.4

mkdir -p /lib/modules/misc && cp cloop.ko /lib/modules/misc/
depmod -a
mknod /dev/cloop b 240 0

# need to install zlib_inflate kernel modules

insmod cloop.ko file=/var/chroot/knoppix2/knoppix/KNOPPIX/KNOPPIX

mount -o ro /dev/cloop compressed/
cp -Rupv compressed/* source/

After going through that I was able to chroot into knoppix. (Of course, I had added it to the schroot.conf file.)
The programs worked fine; however there was no internet connectivity despite mounting the same shared files in fstab that worked for other chroots.
