NixOS on WSL2

Welcome to your new NixOS-WSL system!

Please run `sudo nix-channel --update` and `sudo nixos-rebuild switch` now, to ensure you're running the latest NixOS and NixOS-WSL versions.

If you run into issues, please report them on our Github page at https://github.com/nix-community/NixOS-WSL or come talk to us on Matrix at #wsl:nixos.org.

❄️ Enjoy NixOS-WSL! ❄️

Note: this message will disappear after you rebuild your system. If you want to see it again, run `nixos-wsl-welcome`.
