Like some other commenters, I do not understand why using a cached binary isn’t sufficient. Why not use the mold3 binary and build that first, and then cache it and never rebuild it again? I’m guessing it has to do with hermiticity and build provenance guarantees in your distro.
Do you have any reading material that you can share that might help me understand better? Docs for the distro, or an issue tracker I can search through?
