Sandro 🐧: I had basically

    wsl = {
      enable = true;
      defaultUser = "dkahlenberg";
      #interop = {
      #  register = true;
      #  preserveArgvZero = true;
      #};
      #nativeSystemd = true;
      docker-native = {
        enable = true;
      };
    };
    # https://github.com/nix-community/NixOS-WSL/discussions/71
    security.sudo.wheelNeedsPassword = true;

Maybe it contributed that I had added the new defaultUser with a uid of 1000, which is also the default for the nixos user ?

Enabling the docker-native module might not be even necessary with native systemd anymore - it was mainly just a workaround for docker desktop being unable to start the proxy binary inside NixOS itself, so it might work now without the syschdemd container in the way

docker-native does not seem to be the problem in my case, as soon as I reenabled the nativeSystemd setting (see https://github.com/573/nix-config-1/blob/dcc37f6/nixos/base/nixoswsl.nix#L24) the problem returned: wsl --shutdown then wsl.exe -d NixOS no interactive shell opened anymore.

nzbr (they/it) For what you wrote about docker-native, does that mean I will have the native docker automatically then (don't want to depend on docker desktop) ?

nzbr (they/it): I have to try, right now (https://github.com/573/nix-config-1/blob/04a3c80/nixos/base/nixoswsl.nix#L25) I have nativeSystemd explicitly set on false.

For docker (enabled) I have the native (non-desktop) version and even the binfmt-setting enabled.

With this I could successfully wsl --shutdown and wsl -d NixOS again. Only thing I did differently was chowning all /home/nixos to nixos user and my home dir to my user as well as deletig /etc/passwd and /etc/group entries concerning these prior nixos-rebuild.

EDIT: Using shopt -s dotglob; chown -R nixos:users /home/nixos; shopt -u dotglob to be entirely correct: Only thing I did differently was chowning all /home/nixos to nixos user and my home dir to my user as well as deletig /etc/passwd and /etc/group entries concerning these prior nixos-rebuild.
