Ex-Systems-researcher and NixOS consultant working with Numtide. Maintainers of projects around nix including sops-nix, nixpkgs-review, nix-direnv, nix-update, nixos-shell, nixos-anywhere.
If you ask three NixOS users what their favorite NixOS deployment tool to update a NixOS system is, you might get four answers.

In this talk, we will introduce two tools that can simplify and automate the installation of NixOS on any machine with Linux and SSH access: disko and nixos-anywhere.
