| # As we do not use the Cachix cache containing the artifacts built by developers in this workflow, | ||
| # building the node-installer-image ensures that the whole transitive closure of the packages we build (i.e. everything | ||
| # except what's in cache.nixos.org). Therefore, building this ensures that the kernel, image, IGVM, runtime and the image itself | ||
| # is reproducible across individual builds (as the --rebuild flag is used, causing Nix to rebuild the node-installer-image derivation) | ||
| # and across independent builds on Ubuntu 20.04 and 22.04 (which also test the reproducibility of the transitive closure of our packages, as no shared | ||
| # cache is present between the two machines) | ||

| # Usually we would define the matrix outputs here, but as GitHub Actions don't seem to allow per-combination outputs, | ||
| # we'll write the outputs without defining them here. See https://github.com/orgs/community/discussions/17245#discussioncomment-3814009. | ||
