Privacy-preserving way of counting Tails installations
Cf. the countme proposal of Lennart Poettering for Fedora:
For Tails, we could send a “countme” along with the fetch of the security update feed every time a persistence is mounted in a new month, based on the “Last mount time” of /dev/mapper/TailsData_unlocked.
This would allow us to count the unique installations of Tails with persistence used in a given month (or week) in a privacy-preserving way.
It would complete the picture that we already have on:
- Boot counts
- Downloads (
I can’t imagine how we could count the number of installation of Tails without persistence but we have data about the portion of Tails users with persistence elsewhere already (WhisperBack reports).
