When generating values for the services.nsd.zones attribute using values
from pkgs, we'll run into an infinite recursion because the nsd module
has a condition on the top-level definition of nixpkgs.config.
While it would work to push the definition a few levels down, it will
still only work if we don't use bind tools for generating zones.
As far as I could see, Python support for BIND seems to be only needed
for the dnssec-* tools, so instead of using nixpkgs.config, we now
directly override pkgs.bind instead of globally in nixpkgs.
To illustrate the problem with a small test case, instantiating the
following Nix expression from the nixpkgs source root will cause the
mentioned infinite recursion:
(import ./nixos {
configuration = { lib, pkgs, ... }: {
services.nsd.enable = true;
services.nsd.zones = import (pkgs.writeText "foo.nix" ''
{ "foo.".data = "xyz";
"foo.".dnssec = true;
}
'');
};
}).vm
With this change, generating zones via import-from-derivation is now
possible again.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
