Issue with nixos system build

Help
1

When trying to make nixos system image I get strange error while building system tarball:

[root@nixos:~/img]# NIXPKGS_ALLOW_UNFREE=1 NIXOS_CONFIG=$(pwd)/configuration.nix nix-build image.nix
these 5 derivations will be built:
  /nix/store/67iy6x3zy47lx2zpisssvvyglrajdnfi-closure-info.drv
  /nix/store/nadm07c5fiqd6sybmd05i12r4ywr6ssj-ext4-fs.img-aarch64-unknown-linux-gnu.drv

What does it mean?

Can you also share image.nix and all the dependencies? Or at least some minified version that still produces the error?

Yes, of course. Here is the minimal configuration.nix to reproduce error:

{config, pkgs, modulesPath, ...}:
{
  boot.loader.grub.enable = false;
  boot.loader.generic-extlinux-compatible.enable = true;
  fileSystems = {
    "/" = {
      device = "/dev/disk/by-partlabel/rootfs";
      fsType = "ext4";
    };
  };
  system.build = {
    tarball = pkgs.callPackage <nixpkgs/nixos/lib/make-system-tarball.nix> {
      storeContents = [
        {
          symlink = "/bin/init";
          object = "${config.system.build.toplevel}/init";
        }
      ];
      contents = [];
      compressCommand = "cat";
      compressionExtension = "";
    };
  };
}

you can reproduce issue running nix-build '<nixpkgs/nixos>' -A config.system.build.tarball -I nixos-config=./configuration.nix. My nixpkgs’s svn-revision is 357597.607178a179d.

@tanshihaj I’m running into the same error. Did you ever figure this out?

I ended up doing something a little different, which works:

system.build.tarball = pkgs.callPackage "${toString modulesPath}/../lib/make-system-tarball.nix" {
  storeContents = [
    {
      object = config.system.build.toplevel;
      symlink = "/run/current-system";
    }
  ];
  extraCommands = pkgs.writeScript "extra-commands.sh" ''
    mkdir -p boot dev etc proc sbin sys
    ln -s ${config.system.build.toplevel}/init sbin/init
  '';
  contents = [];

  compressCommand = "gzip";
  compressionExtension = ".gz";
  extraInputs = [ pkgs.gzip ];
};
