Is it possible to set containers.<name>.config from one of the generated nixosConfigurations?

[bjeanes]

I have a NixOS server configured via my snowfall-lib flake on which I want to run a systemd-nspawn machine via containers options. I'm curious if it is possible to wire in its config from a Snowfall-defined system. I see that systems is passed in as an argument to each system module, but in my brief experimentation I couldn't see how to reference one of those systems in a way that worked.

Is this possible?

Thanks for the great project :)

nixos modules get called with an inputs arg, which has inputs.self.nixosConfigurations. I use it to construct services.prometheus.scrapeConfigs by looking at all the config.services.prometheus.exporters for each configuration in inputs.self.nixosConfigurations.

Am I understanding correctly in saying you're trying to do something roughly analogous to:

containers.myContainer = {
  # ...
  config = inputs.self.nixosConfigurations.myOtherMachine;
};

Essentially, yes, though that was the first thing I tried and it didn't appear to comply with the expected interface.
