When inlining a module with a problematic declaration, you usually get
get a not-so helpful error like this:
$ cat flake.nix
{
description = "A very basic flake";
inputs.nixpkgs.url = path:../.;
outputs = { self, nixpkgs }: {
nixosConfigurations.foo = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
({ lib, ... }: { services.wrong = 2; })
{ services.nginx.enable = true; }
];
};
};
}
$ nixos-rebuild build --flake .#foo -L
error: The option `services.wrong' does not exist. Definition values:
- In `<unknown-file>': 2
While it's certainly possible to guess where this comes from, this is
IMHO fairly confusing for beginners (and kinda reminds me of the
infamous "infinite recursion at undefined position"-error).
The module-system determines the position of a declaration using the
`_file`-key: this is either `toString path` if `path` is e.g. a value
from `imports = [ ./foo.nix ]` or the file used as `NIXOS_CONFIG` in
`<nixpkgs/nixos>`.
However such a mechanism doesn't exist (yet) for inlined flake modules,
so I tried to implement this in a fairly basic way:
* For non-path declarations, the position of `modules` inside the
`flake.nix` which declares these modules is determined by doing
`unsafeGetAttrPos` on the `modules`-argument of `lib.nixosSystem`.
So the `flake.nix` from above would now raise the following
error-message:
$ nixos-rebuild build --flake .#foo -L
error: The option `services.wrong' does not exist. Definition values:
- In `/nix/store/4vi3nhqjyma73ygs4f93q38qjkhkaxw8-source/flake.nix': 2

Unfortunately there are some regressions in the GPU code that cause
Chromium and Google Chrome to crash, e.g.:

Hopefully this'll be fixed upstream before the final release (there are
bug reports for it) but for the meantime we have to launch the beta and
dev versions with "--use-gl=angle --use-angle=swiftshader".
