This part:

    In guix/git.scm:
       481:21  5 (update-cached-checkout _ #:ref _ #:recursive? _ # _ # _ …)
       367:15  4 (reference-available? _ _)

rings this bell 6d33c1f8061e86d63ab5c9ec75df9c58130c7264.  Hum, indeed
my bad, I missed a corner-case, reviewers too, and the patch had been in
the tracked for weeks.  Arf. :-)

Well, I guess it is now fixed by
94f3831e5bb1e04eeb3a0e7d31a0675208ce6f4c.

Maybe another discrepancy is still around.

Does the usual “guix pull && guix system reconfigure” work?
