It's redundant with `argsOverride.modDirVersion`.

The whole thing is very scuffed and desperately needs a rewrite, but this is an improvement. |
There was a problem hiding this comment.
I'll only comment on the nixos test related stuff.
The change is ok with me. I've kept it when converting from argument to option, but it seems like we don't need it, not in nixpkgs at least. Let's add a proper error message for it though, for outside use. See comment.

It's not used, doesn't build, and seems like the only reason to have `manualConfig` take `stdenv` as an argument.
Reverts NixOS@7c7c83e which was only needed for the minimal-kernel.nix test module and clutters the call site. stdenv can still be overridden with `linuxManualConfig.override { stdenv = ...; }`.
Document the `linux.override` way first, then `linuxManualConfig`. Add a `linux.configEnv` passthru attribute for quickly getting a `make nconfig`-ready shell.
