Tails is a smaller, specialized distribution that recently reached this milestone: https://tails.boum.org/news/reproducible_Tails/index.en.html

Given the goal of Tails to provide a private computing environment that leaves no traces on the host system after shutdown, it's especially valuable to be able to confirm that the source truly produces the same binary image that the site offers for download.

(If anyone from Tails is reading, please update libccid to 1.4.27!)
