Noticed this when testing guix system build with core-updates. Here's a
small example which reproduces the issue:


(use-modules (guix channels)
             (guix inferior))

(define channels
  (list (channel
         (name 'guix)
         (url "https://git.savannah.gnu.org/git/guix.git")
         (commit
          "e02c2f85b36ce1c733bd908a210ce1182bdd2560"))))

(define inferior
  (inferior-for-channels channels))

(first (lookup-inferior-packages inferior "linux-libre" "5.2.21"))


If you save that as a file then attempt to build it:
