[Nix-dev] reason for changing default of system.copySystemConfiguration to false

[Marc Weber]

true doesn't work in chroots yet.

Minimal test case illustrating the issue:

# nix-env test.nix - the echoed lines should be store path.
# only config1 is one. This is too hacky. We should fix Nix.
let pkgs = import /etc/nixos/nixpkgs {};
in
pkgs.stdenv.mkDerivation {
  name = "test";
  unpackPhase = ''for x in config{1,2,3}; do echo $x ''${!x}; done; exit 1'';
  config1 = /etc/.. + (builtins.substring 1 9999 (pkgs.lib.maybeEnv "NIXOS_CONFIG" "/etc/nixos/configuration.nix"));
  config2 = pkgs.lib.maybeEnv "NIXOS_CONFIG" "/etc/nixos/configuration.nix";
  config3 = builtins.toPath (pkgs.lib.maybeEnv "NIXOS_CONFIG" "/etc/nixos/configuration.nix");
}
