Maybe replace
(symlink target pivot)
by (symlink/remove-old target pivot)
where
(define (symlink/remove-old target link)
"Make a symbolic link named LINK pointing to TARGET.
If LINK already exists, it will be removed first.
This is not an atomic operation."
(catch 'system-error
(lambda ()
(symlink target link))
(lambda stuff
(if (= (system-error-errno stuff) EEXIST)
(begin
;; remove old link and retry
(delete-file link)
(symlink/remove-old link target))
(apply throw stuff)))))
?
