The preparing your system for Stackage page[1] has those auto-updated links
available (e.g., GHC 7.8 exclusive is [2]). You already identified the
downside with this: you may magically be upgraded to a new version of a
package. If you really want to do this, you can, but my recommendation is
to manually decide to upgrade your Stackage snapshot consciously instead of
letter an arbitrary Jenkins build server make the decision for you.
