chown does not change the ownership of a symlink, only that of the
pointed-to entity:

    $ touch titi
    $ ln -s titi toto
    $ sudo chown root:root toto
    $ ls -l titi toto
    -rw-r--r-- 1 root   root   0 Apr 30 18:55 titi
    lrwxrwxrwx 1 ymorin ymorin 4 Apr 30 18:55 toto -> titi

So the symlink's ownership is not modified.

Yann E. MORIN.
