SubjectRe: CD Filesystem still broken!
OK, I have looked into this and here is what I found...

To test the problem I used my Official Debian 1.3.1 CD #1 of 2, and I
also used an old DOS video game CD (Wing Commander II and Ultima Underworld -- not that it matters). I booted into MS-DOS 6.22 and used an old utility I had called "SWEEP" that recursivly descends directories executing the specified command. I did a "SWEEP DIR /ON > D:/FILE" to get a recursive list of all files on the CD. I then rebooted into Linux, and did a "mount /dev/hdd /cdrom0 -t iso9660 -o defaults,noauto,ro,norock" to mount the CD, and then I did an "ls -R1 /cdrom0 > /tmp/scum". I copied the file listings I had created under DOS to /tmp, rand Dos2Unix on them. I then converted them to all lower-case, and did a bit of minor magic to remove non-problems from the diff.

For the Debian CD, I saw the following:

--- /tmp/scum Tue Oct 28 23:45:56 1997

This, however, does not seem to be a problem with the iso9660
filesystem when mounted with "norock", since in each case, the file
"trans.tbl" says the following:

F INSTALL.HTML;1 install.html
F BOOT.CATALOG;1 boot.catalog
L README.SOURC;1 README.source-unpack ../doc/source-unpack.txt

So for this case, the only problem is that whatever was used to make the CD screwed up a few file names during the long name->8.3 translation.


Next, I checked the video game CD. No problems, both DOS and Linux listed the exact same files. I am glad to report, therefore, that I was completely unable to reproduce the problem you describe. Perhaps you could be so kind as to substantiate your bug reports in the future with conclusive evidence demonstrating the problem. I could have used my time doing something more productive after all...
