Nice idea!

I would suggest to send an email to guix-devel explaining how to
reconfigure using ’core-updates’ for testing and then report the
potential issues.

As an example:

Then, the missing from my manifest are:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --branch=core-updates \
       -- weather -m ~/.config/guix/manifests/emacs.scm --display-missing

[...]

Substitutes are missing for the following items:

Well, from https://ci.guix.gnu.org/ let click on the “screen”
(dashboard) under Action and then in the search bar, let type “ocaml-”
thus it display all the red.  Let pick one red: ocaml-angstrom-0.15.0,
then “Show more“ then the red cross and we are at ocaml-ppxlib-0.25.1.
Let click to ‘raw’, bottom, the error seems:

--8<---------------cut here---------------start------------->8---
+  egrep: warning: egrep is obsolescent; using grep -E
--8<---------------cut here---------------end--------------->8---

probably because the update of grep from 3.6 to 3.8.  Then, I have my
homework at fixing these OCaml packages… if no one beats me.. :-)
