feat: add Tails support

[lengau]

Summary

Tails (The Amnesic Incognito Live System) is a Debian-based, security and privacy-focused Linux distribution that is designed to be booted as a live system from a USB drive or DVD. It routes all internet traffic through the Tor network and leaves no traces on the host machine. Tails is used by journalists, activists, whistleblowers, and privacy-conscious users worldwide.

Lifecycle Data Source

Tails has a versioned release cycle. Each major version is supported until the next major version is released. Tails releases a new major version roughly once per year, and older major versions are quickly deprecated. There is no long-term support concept — users are expected to always run the latest release.

Machine-readable data:

The endoflife.date API provides structured lifecycle data:

• API endpoint: https://endoflife.date/api/tails.json
• Sample data (as of 2026-04-21):
  • Tails 7: released 2025-09-18, EOL not yet set (current)
  • Tails 6: released 2024-02-27, EOL 2025-09-18 (succeeded by Tails 7)
  • Tails 5: released 2022-05-03, EOL 2024-02-27
  • Tails 4: released 2019-10-22, EOL 2022-05-02

Notes

• Each major version of Tails is supported only until the next major version is released, making the effective lifecycle ~12-18 months per major release.
• Tails has no LTS concept and does not backport security fixes to older versions; users must upgrade.
• The Tails release calendar at https://tails.net/contribute/calendar/ provides forward-looking scheduled dates, which could be useful for automated data collection.
• Tails is primarily distributed as a live image and not "installed" in the traditional sense, but it still has a meaningful version lifecycle for security purposes.
