There seems to be also an error in nixpkgs, where building nixos results in infinite recursion, but it seems to be independent of this issues, as error persists, even if i rebase on nixos-unstable branch??

this seems to concur with the --show-trace

actually, the other offending line is in locale.nix:

    services.geoclue2.enable = mkIf (lcfg.provider == "geoclue2") true;

I think that's setting to enable, which then causes the geoclue2 to reset the provider to geoclue, which then causes infinite recursion.

[jonringer]

Seems like the main issue is that we have 2 ways of declaring that geoclue2 should be used:

• services.geoclue2.enable
• location.provider

I think the correct course of action would be to eliminate one of these options. Seeing as location.provider is stringly typed, and only used to set services.geoclue2.enable = true;, I think it can be removed.
