Closes #376820 The issue with providing `moduleMakeFlags` via `passthru` of the kernel package is that when this package gets overriden[1], the `moduleMakeFlags` list still references the kernel without the overrides. This broke e.g. kernel modules of linux-rpi4 which can be reproduced with nix-build --argstr system aarch64-linux -A linuxKernel.packages.linux_rpi4.zfs_2_3 This used to break with Error: modDirVersion 6.6.51 specified in the Nix expression is wrong, it should be: 6.6.51-v8 since KBUILD_OUTPUT referenced the kernel without the changes from `overrideDerivation` that also changes the `modDirVersion`. The new approach is to add the build flags right into `linuxKernel.packages.linux_X_Y`: that way we don't need any hacks to update `moduleMakeFlags` when the derivation with the passthru gets overridden. By using the fixpoint of the package-set, the `kernelModuleMakeFlags` list is correctly updated. E.g. given with import ./. {}; linuxKernel.packages.linux_6_6.extend (self: super: { kernel = super.kernel.overrideAttrs (_: { name = "linux-snens"; }); }) the `makeFlags` is correctly updated: $ nix-instantiate snenskek.nix -A zfs_2_3.makeFlags --eval --strict [ "ARCH=x86_64" "CROSS_COMPILE=" "KBUILD_OUTPUT=/nix/store/gsp68549k1aqbwxwczpgw67w5jjn4shw-linux-snens-dev/lib/modules/6.6.74/build" ] [1] E.g. `linux-rpi4`.
