We need this all, only if we make some Knoppix like system...

for the record _I_ said this:
  If we make a DVD, on this DVD will be the normal 'KNOPPIX' directory with
  the normal big KNOPPIX file. From this DVD you can burn a normal
  Knoppix-CD with a mkiso and a cdrecord on the fly with a normal pipe.

If you like to make a remastered Knoppix, you need space (>1GB) and you can't
use the pipe...
