This adds a new configuration option to Nix, `always-allow-substitutes`, whose effect is simple: it causes the `allowSubstitutes` attribute in derivations to be ignored, and for substituters to always be used. This is extremely valuable for users of Nix in CI, where usually `nix-build-uncached` is used. There, derivations which disallow substitutes cause headaches as the inputs for building already-cached derivations need to be fetched to spuriously rebuild some simple text file. This option should be a good middle-ground, since it doesn't imply rebuilding the world, such as the approach I took in https://github.com/NixOS/nixpkgs/pull/221048 |
