+;; list is used, but also a few older versions, when a guix from this package is
+;; used to build something also depending on guix.
+;;
+;; Therefore, if, by accident, you set this package to a non-existent commit ID,
+;; it is insufficient to simply correct it with the latest commit.
+;; Instead, please push one commit that rolls back Guix to before the mistake,
+;; and then another that points to the first one. That way, the faulty commit
+;; won't appear on the linked list.
