[Nix-dev] nixops: argument list too long

[Eike]

It turns out, that it is my tex package. If I remove it, it deploys
successfully. 

Here is a nix file that I tested with:

{
  network.description = "Test";

  trivial =
    { config, pkgs, ... }:
    {

      imports =
      [ <nixpkgs/nixos/modules/installer/scan/not-detected.nix> ];

      boot.initrd.availableKernelModules = [ "uhci_hcd" "ehci_pci" "ahci" "usb_storage" "sd_mod" "sr_mod" ];
      boot.kernelModules = [ "kvm-intel" ];
      boot.extraModulePackages = [ ];
      boot.loader.grub.devices = [ "/dev/sda" ];

      fileSystems."/" =
        { device = "/dev/disk/by-uuid/3bafeea6-2e45-4048-b192-436b5a8f4e3b";
          fsType = "ext4";
        };

      fileSystems."/boot" =
        { device = "/dev/disk/by-uuid/f57eea7e-69d2-4629-af51-0fbff1e1a807";
          fsType = "ext2";
        };

      swapDevices =
        [ { device = "/dev/disk/by-uuid/6488f5b6-9412-4c35-9f1d-ae7bc442410e"; } ];

      nix.maxJobs = pkgs.lib.mkDefault 2;

      services.openssh.enable = true;

      environment.systemPackages = with pkgs;
        let
          # see https://nixos.org/wiki/TexLive_HOWTO
          tex = texlive.combine {
            inherit (texlive) scheme-medium collection-latexextra beamer moderncv moderntimeline cm-super inconsolata libertine;
          };
        in [ tex ]; # I disable this packages, deploy to physical machine works

#      deployment.targetEnv = "container"; #works in both cases
       deployment.targetEnv = "none";
       deployment.targetHost = "192.168.1.72";
    };

}


If I remove the tex package, deployment to a physical machine
works. Otherwise the “Argument list too long” error appears. Deployment
to a nixos container works in both cases.

What is going on?

Eike
