nixos/stage-1: add mechanism which lustrates all impurities from / (#17784)
lustrate /ˈlʌstreɪt/ verb. purify by expiatory sacrifice, ceremonial washing, or some other ritual action. - sudo touch /etc/NIXOS_LUSTRATE ⇒ on next reboot, during stage 1, everything but /nix and /boot is moved to /old-root - echo "etc/passwd" | sudo tee -a /etc/NIXOS_LUSTRATE ⇒ on next reboot, during stage 1, everything but /nix and /boot is moved to /old-root; except /etc/passwd is copied back. Useful for installing NixOS in place on another distro. For instance: $ nix-env -iE '_: with import <nixpkgs/nixos> { configuration = {}; }; with config.system.build; [ nixos-generate-config manual.manpages ]' $ sudo mkdir /etc/nixos $ sudo `which nixos-generate-config` … edit the configuration files in /etc/nixos using man configuration.nix if needed maybe add: users.extraUsers.root.initialHashedPassword = "" ? … Build the entire NixOS system and link it to the system profile: $ nix-env -p /nix/var/nix/profiles/system -f '<nixpkgs/nixos>' -A system --set … If you were using a single user install: $ sudo chown -R 0.0 /nix … NixOS is about to take over $ sudo touch /etc/NIXOS $ sudo touch /etc/NIXOS_LUSTRATE … Let's keep the configuration files we just created $ echo etc/nixos | sudo tee -a /etc/NIXOS_LUSTRATE $ sudo mv -v /boot /boot.bak && sudo /nix/var/nix/profiles/system/bin/switch-to-configuration boot $ sudo reboot … NixOS boots, Stage 1 moves all the old distro stuff in /old-root.
