What you have in /etc/fstab will not affect how your disc gets mounted, if you use a complete mount command such as the one you quoted in your first posting, that is, specifying both the dev and the mount dir. This, per the mount(8) man page. But the fstab settings will be used in all other circumstances (like a "mount dir" or "mount dev", or automatic mount by hal/dbus/udev/gnome-mount/Thunar/God knows what else).
Provide your mount command the "norock" option ("-o norock", right after the "-t iso9660"). All entries listed by your "ls -l" command will now have "root" as uid and as gid, and your permissions will be fixed. If that works as i think it should, then modify your fstab file by adding the "norock" option to the 4th field of the relevant line, joined to the other options by a comma (that is, "...utf8,norock"). However, i don't know what inconvenience there might be to having the Rock Ridge ISO9660 extension permanently disabled, since i just now figured all this out, having a similar problem here (mine shows "RRIP_1991A" in dmesg, rather than your "IEEE P1282"; but i suppose that the difference is per disc). I've since tried a couple of other discs, and am not noticing any problem. Read the beginning of the "Mount options for iso9660" section of the mount(8) man page. Search Wikipedia for "IEEE P1282". Incidentally, doing a remount rather than a umount + mount does not seem to work : "mount -o remount,norock <dir or dev>". I've had to unmount and then remount with the desired options. So i may have discovered a flaw in the mount command (i also have a Gentoo Linux system which helped me solve this problem, where i ran into this same behaviour) -- mixed cd mounts with wrong permissions https://bugs.launchpad.net/bugs/448108 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
