Yeah, I do. For debugging mostly :(

Ubuntu has daily snapshots. Not great, but works reasonably well. I tried going down the Nix route, but my team (well, and also myself) struggled with it.

I'd love to have fully bit-for-bit reproducible builds, but it's too complicated with the current tooling. Especially for something like mobile iOS apps (blergh).
