This is not done automatically.  You need to write the commit message
yourself.  Since you’re using Emacs you may be interested in the
Yasnippet snippets we offer for magit.  After enabling them you only
need to inputs “add<TAB>” to get this kind of message (you then need to
complete the package name).

“pre-inst-env” tells Guix to use your custom version of Guix in the same
directory.  “./pre-inst-env guix lint foo” operates on your local “foo”

It would be good to check why it isn’t deterministic.  You can use “-K”
with “guix build --check --no-grafts” to keep the second output.  Then
you can run diffoscope on it.

You can also search the sources for __DATE__ or __TIME__ or maybe
“date”.  Often non-determinism is due to embedded build timestamps.
