I have developed a number of changes to Knoppix 7.0.2 and
used the following procedure to save these changes to KNOPPIX1 and
re-establish persistence:

1. In a normal, bare Knoppix 7.0.2, I establish a LiveUSB with
persistence and develop certain changes and try them out, noting
all the steps necessary.
2. I reboot with the cheatcode 'knoppix noimage' and repeat all
the same necessary change steps.
3. I use Klaus K's formula to capture the ramdisk information in
KNOPPIX1, using all the directories I note using 'ls' in ramdisk and no others.
4. I transfer KNOPPIX1 into the same /mnt-system/KNOPPIX/ directory
as the original KNOPPIX file itself.
5. I delete knoppix-data.img, reboot and re-establish persistence.
6. I am pleased that KNOPPIX1 us now doing its job.

Here's what is not going right for me:
I go through steps 1 through 5 with some different changes and
develop and install KNOPPIX2, but without the success in step 6.

The simplest instances of this are to simply use Install-Components or
Aptitude to bring in Flash or ntfs-3g. The ntfs-3g exercise is the one
Klaus K uses to showcase the stacking of KNOPPIX1, KNOPPIX2,.. etc.
I presume this is supposed to work, but I can't seem to make it so.

Any suggestions as to what to look for are welcome.
