Nix tooling to enable declarative management of non-volatile system state.

Inspired and heavily influenced by impermanence but not meant to be a drop-in replacement.

Docs are available at https://willibutz.github.io/preservation

Depends on NixOS/nixpkgs#307528 (merged, available on nixos-unstable).

This aims to provide a declarative state management solution for NixOS systems without resorting to interpreters to do the heavy lifting. This should enable impermanence-like state management on an "interpreter-less" NixOS system.
