[Nix-dev] Nixos boot fails at stage 1 in virtualbox

Hi,

Thanks for your answer.

NixOS doesn't use /etc/configuration.nix but /etc/nixos/configuration.nix

No I was editing the right file, I made a mistake when writing my mail.

Yes but I don't know why. By default, my
/etc/nixos/hardware-configuration.nix contains :

    fileSystems."/" {
         device = "/dev/sda1" ;
         fsType = "ext4";
    };

When I remove it and instead add the follwing in
/etc/nixos/configuration.nix I have the error.

    fileSystems = [
       {
            mountPoint = "/";
            label = "nixos"
        }
     ];

So the solution was to to just keep hardware-configuration.nix as it is by
default, and add nothing to configuration.nix. That's odd though...
