During cross-compilation, tests are now executed if the test
suite can be executed by the build platform. This is the case
when doing “native” cross-compilation where the build and host
platforms are largely the same, but the nixpkgs’ cross
compilation infrastructure is used, e.g.
<literal>pkgsStatic</literal> and <literal>pkgsLLVM</literal>.
Another possibility is that the build platform is a superset
of the host platform, e.g. when cross-compiling from

For cross-compilation targets that can also run on the

- The `emacs` package now makes use of native compilation which means:
- Emacs packages from Nixpkgs, builtin or not, will do native compilation ahead of time so you can enjoy the benefit of native compilation without compiling them on you machine;
- Emacs packages from somewhere else, e.g. `package-install`, will perform asynchronously deferred native compilation. If you do not want this, maybe to avoid CPU consumption for compilation, you can use `(setq native-comp-deferred-compilation nil)` to disable it while still benefiting from native compilation for packages from Nixpkgs.
- `nixos-generate-config` now generates configurations that can be built in pure
mode. This is achieved by setting the new `nixpkgs.hostPlatform` option.
You may have to unset the `system` parameter in `lib.nixosSystem`, or similarly
remove definitions of the `nixpkgs.{system,localSystem,crossSystem}` options.
Alternatively, you can remove the `hostPlatform` line and use NixOS like you
would in NixOS 22.05 and earlier.
