That's a symbolic link. firmware-linux-free_3.3_all.deb -> ../pool/main/f/firmware-free/firmware-linux-free_3.3_all.deb Useful mostly with Rock Ridge. > In the Supplementary Volume Descriptor (Joliet), that file isn't there. > The directory /firmware is present, but it is empty. Joliet (and plain ISO 9660) do not represent symbolic links. Because Rock Ridge is an add-on to the ISO 9660 tree, there is an empty file in that tree, of which the Rock Ridge attributes tell the story. I wonder why the Debian installation ISOs contain Joliet at all. Are there use cases on MS-Windows for which one would want to unpack files ? Is it certain that all names are short enough for being represented in Joliet without mangling ? (103 characters by -joliet-long.) > So ... Debian CD production may have some kind of problem. If it is a problem, then of program xorriso, of which i am the developer. For now i see none, except the inavoidable confusion caused by empty or missing file, where Rock Ridge mounted on a Unix-ly system shows a working symbolic link. Have a nice day :) Thomas
