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 <profile>/manifest file.
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’re currently running with packages available in a different revision
of Guix. Guix “inferiors” allow you to achieve that by composing
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 (compiled
with
foo B) and Go Z (compiled with foo C). It is technically possible, right?
