  "textContent": "Robin Candau has announced the availability of a bit-for-bit reproducible container image for Arch Linux:\n\n> The bit-for-bit reproducibility of the image is confirmed by digest equality across builds (`podman inspect --format '{{.Digest}}' <image>`) and by running diffoci to compare builds. We provide documentation on how to reproduce this\nDocker image (as we did for the WSL image as well).\n>\n> Building the base rootFS for the Docker image in a deterministic way was the main challenge, but it reuses the same process as for our WSL image (as both share the same rootFS build system).\n>\n> [...] This represents another meaningful achievement in our \"reproducible builds\" efforts and we're already looking forward to the next step!",
