Background:
Here's an abbreviated tally of the cloops saved at /mnt-system/KNOPPIX/
on my current Knoppix 7.7 CeBIT version LiveUSB:
/mnt-system/KNOPPIX/ is a folder or directory on a FAT32 filesystemCode:knoppix@Microknoppix:~$ ls -l -o -h /mnt-system/KNOPPIX | grep KN -rwxrwxrwx 1 root 4.0G Apr 14 06:30 KNOPPIX The basic Knoppix 7 DVD -rwxrwxrwx 1 root 171M Apr 14 06:30 KNOPPIX1 Recent 3d & backup programs -rwxrwxrwx 1 root 7.5M Apr 14 06:30 KNOPPIX2 Flashplugin-nonfree -rwxrwxrwx 1 root 76M Apr 14 06:31 KNOPPIX3 My own tweaks & additions
which has a filesize limitation of just a little over 4 Gb. KNOPPIX, aka
KNOPPIX0, uses virtually all of the 4 Gb capability of a cloop device
on FAT32 to define most all of Knoppix 7 DVD's basic contents.
KNOPPIX1 contents plus KNOPPIX0's plus some auxiliary files would produce
a collection which would be slightly over the 4 Gb FAT32 filesize limit,
hence KNOPPIX1 contents are given their own cloop.
Since there are, at present, eight unique cloop device assignments, there
may be additional KNOPPIX[n]s defined, each having a 4 Gb capacity.
I postulate that KNOPPIX2 is Klaus K's way of providing the CeBIT Knoppix
version with proprietary flash material on the 7.7 DVD using LinuxPro
Magazine's authority to distribute.
KNOPPIX3 is my own current use of Knoppix cloops to make a read-only,
compact representation of my own tweaks & additions initially to a
read-write, not-compact, reiserfs persistence file, KNOPPIX-DATA.
I use a small bash program to do this.
See the following, where MakeOverlay is what I now call save.overlay:
http://knoppix.net/forum/threads/306...x-7-2-LiveUSBs
Premise:
With the advent of overlayfs, and especially using a 4.0-or-later kernel
there are opportunities to further aggregate & compact Knoppix cloop material.
It seems plausible that another small bash program might be similarly
useful to further agregate the initial contents K'1, K'2 and K'3 into
a new but larger but still-much-less-than-4 Gb re-defined K'1. The following
two references lead me to believe this:

Immediate project:
I have in mind eventually defining a small bash program which I might call
merge.overlays, using the cited material and some additional ideas in:
