Update Churn & Compression Analytics#
Project Bluefin measures download byte delta, layer reuse efficiency, and compression statistics between consecutive stable releases.
Using Chunkah and the zstd-chunked container layer format,
operating system updates are segmented into fine-grained package intervals so clients download only specific chunks containing changed packages.
Methodology, Privacy & Opt-Out
Counting Methodology#
Every Project Bluefin count comes from countme.projectbluefin.io
First-party Countme Service & Privacy Guarantees#
Project Bluefin images participate in direct weekly countme reporting via systemd services targeting
https://countme.projectbluefin.io/metalink.
- Cohort measurement: Uses installation age buckets (1: first week, 2: 2–4 weeks, 3: 5–24 weeks, 4: >24 weeks) calculated locally from an installation epoch timestamp.
- Privacy guarantees: Transmits only image name, tag, flavor, architecture, and age bucket. No machine ID, IP address, username, or persistent identifier is sent or logged.
Opt-Out Instructions#
To disable Project Bluefin countme reporting, disable the systemd timer:
sudo systemctl disable --now bluefin-countme.timer
To disable upstream Fedora countme:
To disable Homebrew analytics:
