[Nix-dev] recursiveUpdate for lists

[Tomasz Czyż]

Basically I created simple wrapper function to create systemd services.

The function produces something like

{
  my-service={
    requires=["service1.service"];
  };
}

I want to customize it after with recursiveUpdate function, I want to merge
it with

{
  my-service={
    requires=["some-other.service"]
  };
}

I tried to avoid module stuff as in that case if I understand correctly I
need to prepare my description of systemd service on top of standard nix
systemd config structures which is probably big waste.

What do you think?
