The procedure in that article is for Knoppix <= 3.7.
The file /cdrom/KNOPPIX/KNOPPIX was mounted cloop
and most of / was symlinks pointing into it.
/ itself was ramdisk, created at boot time.
Starting with Knoppix 3.8, / is a UNIONFS with
some directories from the cloop-mounted KNOPPIX
file and others as before, in ramdisk.
It's a great article, but does it still work with
Knoppix > 3.7?
I haven't seen any remastered 3.8.2's yet, and
haven't had time to do it myself.
Things are missing from article/7246, and from
the similar discussions in _Knoppix Hacks_ and
the knoppix.net forums. After you unpack KNOPPIX
into a directory on your ext3 FS, note the size with
du -s .
Now apt-get {update,upgrade} and make your little
tweaks. Notice how much the "du -s ." size has grown.
If you make a new KNOPPIX with create_compressed_fs,
it's too big now. "Hack #95 Trim the Fat" suggests
removing packages and running apt-clean, but it is
never enough. There's more fat, but where?
Can you safely remove /var/cache/apt/pkgcache.bin ?
