The full trace is included at the bottom. I am trying to use flake-compat as a shim to generate a configuration.nix for nixos-install since the installer seems to be broken in many weird ways.

I tried to debug the installer, but the issue is fundamentally with the output of the flake, and it doesn't seem to set up a new system correctly. For example, writing the ISO's fstab to /mnt/etc rather than the one generated by my flake's activation script.

I have some glue code (bash) around these lines:

cat <<- EOF > "$root_dir/etc/nixos/configuration.nix"
	(import (builtins.fetchTarball {
		url = "$FLAKE_COMPAT_TARBALL_URL";
		sha256 = "$FLAKE_COMPAT_TARBALL_HASH";
	}) {src = "$flake_path";}).defaultNix.nixosConfigurations.$host_name.config
EOF

Obviously $root_dir, $flake_path, and $host_name are handled elsewhere in the shell script. The flake is pre-built and sent over to the store at /mnt/nix/store before running nixos-install (on $root_dir which is /mnt).

I have attempted to follow the trace myself to determine if I can do something about it -- alas I am not experienced enough. I feel that it is worth note that I perform an explicit import of nixpkgs (that is a link to my flake.nix).

I would like to know if I am using the wrong attribute path (in configuration.nix) or something, and if the issue is that nixpkgs.pkgs is not being evaluated properly. If it is being evaluated correctly by flake-compat, I would like to know what wants nixpkgs.pkgs, I do not see any occurrence in my code.

Thanks.

When running nixos-install, I see the following:

The full trace is included at the bottom. I am trying to use *flake-compat* as a shim to generate a `configuration.nix` for `nixos-install` since the installer seems to be broken in many weird ways. *I tried to debug the installer, but the issue is fundamentally with the output of the flake, and it doesn't seem to set up a new system correctly. For example, writing the ISO's `fstab` to `/mnt/etc` rather than the one generated by my flake's activation script.* I have some glue code (bash) around these lines: ```nix cat <<- EOF > "$root_dir/etc/nixos/configuration.nix" (import (builtins.fetchTarball { url = "$FLAKE_COMPAT_TARBALL_URL"; sha256 = "$FLAKE_COMPAT_TARBALL_HASH"; }) {src = "$flake_path";}).defaultNix.nixosConfigurations.$host_name.config EOF ``` Obviously `$root_dir`, `$flake_path`, and `$host_name` are handled elsewhere in the shell script. The flake is pre-built and sent over to the store at `/mnt/nix/store` before running `nixos-install` (on `$root_dir` which is `/mnt`). I have attempted to follow the trace myself to determine if I can do something about it -- alas I am not experienced enough. I feel that it is worth note that I perform an [explicit import of *nixpkgs*](https://github.com/spikespaz/dotfiles/blob/748b6d7142777c75bd48f0d6247fc4cd3f18fe2f/flake.nix#L52-L61) (that is a link to my `flake.nix`). I would like to know if I am using the wrong attribute path (in `configuration.nix`) or something, and if the issue is that `nixpkgs.pkgs` is not being evaluated properly. If it is being evaluated correctly by `flake-compat`, I would like to know what wants `nixpkgs.pkgs`, I do not see any occurrence in my code. Thanks. When running `nixos-install`, I see the following: ``` error: The option `nixpkgs.pkgs' is used but not defined. … while evaluating the attribute 'mergedValue' at /mnt/nix/store/x20avpqcrk6my01n6h1blfslb6l4imw2-source/lib/modules.nix:747:5: 746| £ Type-check the remaining definitions, and merge them.
