Forward slashes in filenames 2899

? That might *seem* correct, but according to my investigations with "mkisofs -r -J -relaxed-names -o temp.iso povray" , it isn't. The directory povrayhas several subdirectories and subsubdirectories, and is not present within the filename records in the iso9660 filesystem mkisofs generates. I'm pretty sure that ISO9660 has its own method for specifying whether something is a directory or file or what, and doesn't enter into it--thes you see are put in by the kernel's iso9660 module and-or the VFS.

Furthermore, if I edit temp.iso with a hex editor and replace a random character in a filename or directory record with '-' , I can still mount the ISO with -o loop and look at it. The directory or filename I changed becomes unreadable (ls says "Inv-der: no such file or directory") in the normal case. If I pbutt -o loop,norock,nojoliet , then the kernel's ISO9660 filesystem module translates the into a . , and the file or directory becomes readable again. This may not be totally relevant to Grunff's problem, since mkisofs is probably more anal about things than whatever the original MacOS 9 thing that wrote these CDs was, but it's the best that I could come up with since I don't have access to a MacOS 9 machine right now.

I think Grunff might want to say which kernel he's running. The ISO9660 code shouldn't have changed much recently, but I'm running 2.6.10 vanilla here and older kernels may show different behavior wrt "weird characters" in the filename.

What would really help me here is the ISO file generated from the original CD. Unfortunately, ISOs are huge, and it's probably difficult or impossible for Grunff to upload one of these files to me. Grunff, if you want to try it anyway, holler at my e-mail (mind the SPAN TRAP), and I'll try to work out something so you can upload ~700M of data via scp to me. It might even be possible for me to do something with only the first ~20M of data, but having the whole ISO would cut down on the number of weird problems I'd be likely to run into.
