Ah. I did install patched guix into the system (and that's how
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=50090).

I still don't quite understand if channel we pull from also should be patched.
Let's assume it should:

  $ LANG=C ./pre-inst-env guix pull --url=. --commit=e9029ed5eae45ee8f53f055ee66f9bce353cac84 --root=guix0
  guix pull: error: root=guix0: unrecognized option

I'm not sure what --root= does. Is it a user name? Or a profile name?
