They ask you to insert a DVD so that its filesystem can be mounted and you can access the files on that DVD. > This is not always - or even usually - equivalent to "mount -o loop". huh? Its almost always the same. Unless you are using the DVD for something non-standard. (years ago I used to write .tar files directly to floppy media. I suppose you could arrange to use a DVD in the same fashion, but most people don't.) Most DVDs contain ISO (or UDP) filesystems (which for the sake of this argument are equivalent). > The jigdo documentation is not very good, > which is not surprising if the people writing it share your approach. I had no trouble using it. It is surprisingly simple. -- Kevin J.
