Someone tried that on help-guix. The idea was to recreate a Python environment. It was an extensive use of inferiors: one inferior per package. We already discussed that when discussing how to recreate a profile from a /manifest file.=20=20 Just to point the manual about inferiors: --8<---------------cut here---------------start------------->8--- Sometimes you might need to mix packages from the revision of Guix you=E2=80=99re currently running with packages available in a different rev= ision of Guix. Guix =E2=80=9Cinferiors=E2=80=9D allow you to achieve that by com= posing different Guix revisions in arbitrary ways. --8<---------------cut here---------------end--------------->8--- Therefore, I want esbuild X (compiled with GCC A and foo A), GCC Y (compile= d with foo B) and Go Z (compiled with foo C). It is technically possible, right? Cheers, simon
