That's a good idea.  I've added a squash commit with

               ;; Upon first boot the /hurd symlink does not exist; it is
               ;; created during activation: Hard-code the .../hurd store file
               ;; name.

In other news, I've been playing with at "devel-hurd.tmpl" system and
just succeeded to build gnu-make-boot0!  I still need sort of a hack to
include %bootstrap-gcc etc, but this gives me good hopes that we'll be
able create a functional VM to build substitutes after merging!

Greetings,
