    Also because you can't do a proper job from user-mode. The only tool available
    is readlink, but readlink and followlink are different operations in the VFS
    interface. In other words, its possible for a filesystem to put one thing in a
    symlink as far as readlink goes, and do another when you try to follow it.
    /proc has many examples of this, and it is not unique.

    You may be able to do it if you add an appropriate syscall.
