Hey!

Given the enthusiasm expressed on IRC, I went ahead and pushed.  :-)

  ff3ca7979e channels: Add patch for <https://bugs.gnu.org/41028>.
  053b10c3ef channels: Add mechanism to patch checkouts of the 'guix channel.
  4ba425060a channels: Add 'latest-channel-instance'.

So… it might be that today is merge day?

[Message part 4 (text/plain, inline)]

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:


→ guix build -f test.scm
