USB booting :: How to reconfigure the minirt image

This really is turning into a never-ending saga.
I was puzzled why with all of the multitudinous changes I had made to the linuxrc in the unzipped minirt24.gz, not one single change seemed to have been made to the performance of the boot -- always the same error, always the same time.
So, I commented out this line in linuxrc

Code Sample

echo -n "${CRE}${BLUE}Looking for CDROM in: ${MAGENTA}$i${NORMAL} "

but it still showed up when I rebooted.
Now this is intruiguing. So, where is the boot getting its instructions from?
Please help -- I'm really very lost here.

Whoa. You sure you overwrited the previous image?

Yes, I am sure.
Certainly the changes I make in linuxrc are there when I open up linuxrc the next time to make the next change.
I might just try a test where I substitute linuxrc with a totally empty file (of the same name) and zip up the minirt24 and see how it works on bootup.
My belief is that it will not make any difference.
I'm going to try this and I'll post back.
When I made these sort of changes to intrd.img on other distros I always had to re-configure the initrd.img (dpkg-reconfigure or mkinitrd) but I'm not doing anything here other than zipping things up and trying again.
Am I missing anything?

No.. But some text is shown twice, first in linuxrc and then during knoppix-autoconfig..

OK, I renamed linuxrc to something else and substituted it with a totally empty text file, unmounted the "new" minirt24, zipped it and copied it to the boot directory of my DSL partition.
Sure enough, the boot just went exactly as it has done for the last two days -- absolutely no difference.
Hmmm.... what to do next?
