Symbolic links do not have permissions (unless you do something like
work with advanced filesystem interfaces or special circumstances). A
symbolic link is not really a file, it is a pointer to the real file.
The real file permissions are what rule. You wouldn't want to have to
set permissions via both sym links and the real link, imagine the
security nightmare if making a sym link to any hard link would ignore
hard link permissions. The directories containing the hard link, and the
hard link itself, still enforce their permissions.
