I could narrow it down somehow. This commands drags the bootstrap and fails: --8<---------------cut here---------------start------------->8--- guix build --target=<any-target> alsa-lib --8<---------------cut here---------------end--------------->8--- while this one doesn't: --8<---------------cut here---------------start------------->8--- guix build --target=<any-target> alsa-lib --no-grafts --8<---------------cut here---------------end--------------->8--- Not sure how to go further. Adding Ludo and Efraim. Thanks, Mathieu
