`warning: unknown setting 'trusted-users'`

[pwaller]

I'm seeing warnings when I run nix-eval-jobs:

warning: unknown setting 'allowed-users'
warning: unknown setting 'trusted-users'

It would be nice to eliminate them from CI logs. They are a bit mysterious.

Don't think we can actually. Those are coming from libnix.

[Mic92]

Ah. Maybe they are caused by some missing library that would add them into nix-eval-jobs? The first option definitely looks like a spelling mistake though.

The first option definitely looks like a spelling mistake though.

That was a transcription error in the issue body (now fixed).

Your hypothesis about the cause sounds sensible to me. I also forgot to mention the nix-eval-jobs version I'm using, which might be a little outdated - it's the one shipped in nixpkgs NixOS/nixpkgs@c0b1da3, which is nix-eval-jobs-2.22.1.

I hope to try a more recent version at some point.

The issue does occur with the latest nixos-unstable (2.25.0). It is quite easy to reproduce in a standard configuration it seems to me, since I don't think I set trusted-users, but it is the /etc/nix/nix.conf.

This option is defined in:

• src/nix/unix/daemon.cc
61-
62-    Setting<Strings> trustedUsers{
63:        this, {"root"}, "trusted-users",
64-        R"(
65-          A list of user names, separated by whitespace.

Not sure if we can actually link ./src/nix, It's not a library.

We could potentially a dummy setting to shut up nix.
