(make-symbolic-link "~/.emacs" "/:/tmp/~eggert")

# ls -l /tmp
[...]
lrwxrwxrwx  1 albinus albinus     20 Aug 20 20:24 ~eggert -> 
/home/albinus/.emacs

(rename-file "/:/tmp/~eggert" "/:/tmp/~albinus")

# ls -l /tmp
[...]
lrwxrwxrwx  1 albinus albinus     20 Aug 20 20:24 ~albinus -> 
/home/albinus/.emacs
