• Arch Linux now has a reproducible container image

    From LWN.net@86:200/23 to All on Tue Apr 21 06:40:26 2026

    Robin Candau has announced
    the availability of a bit-for-bit reproducible container image for
    Arch Linux:

    The bit-for-bit reproducibility of the image is confirmed by digest
    equality across builds (podman inspect --format '{{.Digest}}'
    ) and by running diffoci
    to compare builds. We provide documentation on how to reproduce this
    Docker image (as we did for the WSL image as well).

    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).

    [...] This represents another meaningful achievement in our
    "reproducible builds" efforts and we're already looking forward to the
    next step!
