Sane System Management with NixOS - I Do Declare!
summary
Nix and NixOS promise a single declarative file that reproduces a whole system: kernel options, services, user packages and dotfiles, so a new machine boots to the same state in minutes. Packages live in a read-only Nix store with symlinked profiles, enabling atomic rollbacks and per-user installs; builds come from a binary cache via Hydra (or build-from-source), and the distro reports ~98.8% bitwise reproducible ISOs. A quick VM build proves changes before reboot.
