Bootable NixOS on USB with GNOME and ready to login

I need to create a USB with NixOS already configured with GNOME and ready to login with username and whatever apps I specify. I also will set it up to connect to a specific vpn. Any templates for this to get started?:wink:

I find the installation-cd-minimal.nix, but that’s for an install USB.

You probably want to use the raw-efi generator from https://github.com/nix-community/nixos-generators, and then dd it onto your usb.
