You can safely omit it for anyting newer. It is actually detrimental for most reasonable OS's, as it strips some of the flexibility out of the iso9660 standard - it's more like an extension of a subset of the standard, rather than a standard + extension. I think max filename length and character set are among the things that this affects. -r is really what I think you want - you want the Rock Ridge extension to the iso9660 standard, which gives you filenames up to 31(maybe?) characters, some flexibility WRT character set, and a standardized permissions set (the standardized part sucks for file systems that actually understand permissions, but it tries to be interoperable). > I have not been able to get it to work at all for MacOS names, let > alone file types. By this, do you mean the HFS+ special bits, or something else? I am not sure that all of these are actually translateable to iso9660, but there are some extensions (-apple, -hfs) that can be used. Maybe I'm not understanding what you mean, not being a Mac guy much anymore. Oh, duh - thought about it again. You mean the Mac TYPE bit set on files, right? The thing that lets you click a file and have the right program open it? If you use -apple, mkisofs attempts to guess this from the magic info in the beginning of the file, and store it in the directory record. If it's not working, you can create a map file, and use some argument (it might be --mapping-file, or maybe --mapping, to use that file - I don't have the manpage handy to check all the syntax; I'm going from memory of six months ago, when I went through a 'burn everything to disk' period and spent a lot of time with that manpage :) I don't think woody's mkisofs is that smart about the things you're wanting to do - the one in sarge/sid is much better, and I highly recommend upgrading if you haven't yet.
