I see no console messages when running an offload build from a manifest containing an inferior. It's only when the inferior is included that the logging disappears. A sample manifest exhibiting the issue:
$ guix build --system=aarch64-linux --manifest=test.scm --8<---------------cut here---------------start------------->8--- (use-modules (guix channels) (guix inferior)) (define channels (list (channel (name 'guix) (url "https://git.savannah.gnu.org/git/guix.git") (commit "312f1f41d3f3f3e5d2c36ff46920c6dce1c21a17")))) (define (pinned-version name) (car (lookup-inferior-packages (inferior-for-channels channels) name))) (packages->manifest `(,(pinned-version "ungoogled-chromium"))) --8<---------------cut here---------------end--------------->8---
