Description
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
EOFObviously $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:
error: The option `nixpkgs.pkgs' is used but not defined.
