can't generate config without X

[teto]

I am adding support for astroid in home-manager https://github.com/rycee/home-manager/pull/408 (i.e., home-manager will generate astroid config file). My first approach was to copy the default config into home-manager and change some parameters. I want to generate the config instead of manually updating it for 2 reasons:

• manually updating is annoying
• one of the strength of nix is rules out impurities. Having a manual config creates state, which may break updates depending on which version of astroid to use

So I have this script

    generateConfig = pkgs.runCommand "astroid-config-template" {} ''
        export HOME=$out
        ${pkgs.astroid}/bin/astroid --new-config
    '';

but it fails because of (I think):

DISPLAY= astroid --new-config                                                                                                                                   
(.astroid-wrapped:14685): Gtk-WARNING **: 23:16:24.072: cannot open display: 

Could astroid be made so that it doesn't need X to generate the config ?

Yes, we need this for the tests too.
