Hi 1ijack,

The magic of KNOPPIX from the compressed cloop read only
file on the CD can be a bit hard to follow. I like doing projects
from the live CD KNOPPIX.

Here is the trick. When you get into the directory
/etc/sane.d and type ls you see blue files.
Now type ll -a
and you will see that these are not real files -- they
are links. So you cannot edit them.

What to do? Well you copy the file -- epson.conf
in to /home/knoppix.

If you try to edit it from your desktop it will say permission
denied. Bummer! The file is a root file. So from the
shell enter the command su. This will make you root.
Now you can edit the file -- if you can manage a console
editor. My favorite is vim -- so study that.
Ok, gvim started from the root prompt wil work.
Make your edits and save this file.
You may want to also save this to a floppy if you do not
have a persistent home.

Now for the weird part: In the read only directory you
cannot add new files or change the files -- remember they are
links to the CD. But you can remove the file link as root.
rm -f /etc/scan.d/epson.conf
And now you can copy your edited file there since KNOPPIX
has alowed a link for that file name.
cp /home/knoppix/epson.conf /etc/sane.d/*.*

Hard to believe but it should work. For fun -- now
go the /etc/sane.d and again type ls.
Low and behold, among all the blue files will be your
white one.

As I mentioned above, all of this can be automated
from a script. But get it working by hand first.

Let me know if you get this to work.

For the new versions of KNOPPIX live CD
Herr Klaus Knopper will allow a method
of file overlay -- translucency -- to allow
new user created files to appear as if they
are on the CD file system.

Best Wishes
