[Nix-dev] [nix-dev] private NixOS modules

[Nicolas Pierron]

Hi Sergey,

We have a some documenation in the NixOS Manual [1] which explains how
to do that.  To make it short, your configuration.nix file should have
an import attribute which is a list of additional modules that you
want to include.
So if you file configuration.nix looks something like (a), you want to
convert it to something similar to (b)

** (a):
{
  services.openssh.enable = true = …;
  …
}

** (b):

{
  imports = [ ./custom-service.nix ];
  services.openssh.enable = true = …;
  …
}
