I'm now running impermanence on NixOS servers. Setting it up was slightly more work, obviously, but it's been... freeing in a sense. My confidence that I can rebuild all servers at any time and that all the peculiarities of my setup are documented have never been higher.
Rather than using a script for setup, I am using disko [0] with nixos-anywhere [1] and a small home-grown script that integrates with 1Password for deployments and it's wonderful, because everything including disk formatting is now purely declarative.
