Actually, it depends on what you mean. You have two ISO images while
mastering KNOPPIX. One is written from the native Debian filesystem and
can be compressed on the fly. The result is the big KNOPPIX file that
takes 99% of the KNOPPIX-CD. Then you need another mkisofs to create the
Knoppix-CD-ISO, together with the boot-floppy, docs, demo files, etc.
The problem is: this external mkisofs run needs to know about the file
sizes. You cannot fool it with a pipe getting data from the process
compressing the internal KNOPPIX volume.

I can imagine a way to work around this problem, using multiple
sessions. The problems:

a) It is not known wheter all BIOS types will boot from multisessions CDs
b) Knoppix' boot image needs modifications to load the KNOPPIX volume from
   a hidden session
c) Klaus' CD mastering scripts need some changes

What about the Xandros guys? If they donate some exemplars, we could
also make good publicity.

Haben Sie einen H�cker gesehen?
