Hi @wespanther. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Nit: CONFIG: 'trixie' in variants.yaml is not tracked by this entry, while the bookworm equivalent (CONFIG: 'bookworm') is tracked under "Debian: codename (default)" at line 376-377. Consider adding a refPath here for consistency:

      - path: images/build/debian-base/variants.yaml
        match: "CONFIG: 'trixie'"
