Reproducable environments using nix
summary
Nix claims to produce bit‑identical builds by pinning inputs and isolating steps; demonstration uses flakes with lockfile pins, dev-shells and mkDerivation to build the same main binary on Ubuntu and NixOS with identical sha256 outputs. It shows producing a runnable VM from ~27 lines of Nix config, bundling apps into Docker or a single executable, and importing a .deb via autopatchElf or running it unchanged inside an FHS wrapper. Learning curve and fragile experimental features are noted.
