feat(countme): ship the shared bluefin-countme reporter

[castrojo]

This image did not report to countme.projectbluefin.io and had no way to, so it counted as nothing.

The reporter is not defined here

os-countme.bst sources it from projectbluefin/common system_files/shared — the same unit, timer and helper every other image ships. This image counts through exactly the same bluefin-countme as the rest of the family and carries no countme code of its own.

Unlike Bluefin, LTS and Dakota, this repo has no common.bst, so the files come from a git_repo source rather than an existing junction.

The preset from common enables the timer, which this image already honours via kind: import into system-preset — no enablement symlink needed, unlike Dakota.

Why os-image-info.bst exists

The reporter reads /usr/share/ublue-os/image-info.json to know which image it is counting. Every other image writes one during its build:

• Bluefin / LTS — build_scripts/90-image-info.sh
• Dakota — include/os-release.yml

This image has neither that file nor a bootc ref to fall back to, because it is a DDI delivered by systemd-sysupdate rather than an OCI image. Without it the reporter exits without sending, which is the correct behaviour but leaves the image uncounted.

Only image-name is declared. A DDI has no container tag or flavor, and the reporter omits fields it is not given rather than sending a placeholder. os-release here is NAME="Bluefin Server" / ID=flatcar, neither of which is a usable repo id.

Dependencies

curl and jq are added explicitly — this image is minimal and had neither, and the reporter needs both.

Follow-ups (filed)

• os-countme.bst pins a branch ref in projectbluefin/common and must be re-tracked #95 — re-track the common ref once feat(countme): report to countme.projectbluefin.io from the images common#1112 merges. Blocking once that branch is deleted.
• Confirm the curl component path in the freedesktop-sdk junction #96 — confirm the components/curl.bst path in the freedesktop-sdk junction.
• Bluefin Server reports no stream identifier to countme #97 — decide whether this image has a stream identifier worth counting, or whether tag=unknown is permanent.

Original note

The git_repo ref is pinned to v2026.08-108-gd46c4df9f..., the tip of the branch in projectbluefin/common#1112. It must be re-tracked to main once that PR merges. I cannot run bst track here to generate the replacement.

If CI reports the curl component path differently in this junction, that is the one line to correct.
