    Make sure that if CD9660 is not compiled into the kernel, cd9660.ko has
    been loaded by root before you try to mount the filesystem as an
    unprivileged user. The kernel tries to load the module automatically,
    but this fails if you're not root or if securelevel has been raised.
    Also be aware that the character set conversion options to
    mount_{cd9660,msdosfs,ntfs} do not always work properly for unprivileged
    users.
