Hi, considering https://bugzilla.novell.com/show_bug.cgi?id=665479 I wonder: Why isn't there a mount option "nosymlink"? >From my little knowledge of UNIX history I think at the time when "nodevs" and "nosuid" ere invented, there did not exist symbolic links. So it might be natural to have a mount option "nosymlink". I don't know if other security problems are remaining unfixed ading this. Also, the mount option will prevent symbolic links from being created through the file POSIX system interface, but not from the kernel-side.
