Back to the issue.

Yes, the whole CD passed the check. Hope, the wrong boot file is not a real problem .

However... in order to make future readers' life a little bit easier.

- I think, that the questionable isolinux.bin boot file is about the initial screen with publisher's data. (O'Reily's hacks URL) So, I have to submit bug report to O'Reilly not to Knoppix?

- testcd seems to be a Knoppix (or higher level) bug. I think it either tests the whole CD's MD5 (not paying attention to files) or is smart enough to decide if the error is significant. In any case the message is confusing in cases like mine.
Do folks have any suggestions before we submit the bug report?
It's not a Knoppix problem really. When you remaster you are supposed to update the file that has a list of proper md5sums. I just forgot to change the md5sums for the file I changed (since it was just background.jpg and I wasn't doing a full remaster). You could submit a bug report to the errata page for Knoppix Hacks on http://www.oreilly.com/catalog/knoppixhks/ if you wanted, but I don't know if it's a major-enough bug to warrant recreating the ISO for subsequent versions since the CD itself runs fine, just that testcd command gives two minor errors.
