You want to use https://nixos.wiki/wiki/Linux_kernel#Custom_configuration when building kernels inside of nixos but for that we would need to know the internal name of the options. I am not sure if we can then export the kernel and tell WSL to use it. |

You can't override the kernel through the NixOS configuration, because the WSL VM uses one shared kernel across all distros. You'll need to put the The I'm sorry that I couldn't help you here |

@nzbr thanks for your effort. The instructioms tell us to build the usb/ip tools besides the kernel.
The linux-tools-virtual apt seems to be just an effort to get better ubuntu support on hyper-v and I would ignote that for now. |

First I customized the kernel provided by WSL2 { pkgs ? import <nixpkgs> {} }:
pkgs.stdenv.mkDerivation rec {

sha256 = "18b5s6kxjnxnfhhh5ywgnxrj4pi8jr0g0bdd9y3vj7qi1q2nz7zw";
};
postUnpack = ''
(cd $sourceRoot
TOP=$(cat scripts/ld-version.sh|grep ^#\!.*bin|awk -F\ '{ print $1 }')
substituteInPlace scripts/ld-version.sh --replace "$TOP" "#!${pkgs.gawk}/bin/awk")
'';
nativeBuildInputs = with pkgs; [

Very very WIP my notes over here for anyone interested in this. The baseline for now is, I was not able to use the kernel built via nix in WSL2, my suspicion it has to do with the gcc version, so probably fixable. Other than that I was able to use something like this: environment.systemPackages = let inherit (pkgs.linuxPackages) usbip; in [
usbip
];in my configuration.nix so once the rest (i. e. running a NixOS WSL instance as elevated windows user) is figured out one could use devices from inside nixos wsl instance. |

I have POC to build a custom kernel with import <nixpkgs> {};
{
kernel = let
tag = "5.15.146.1";
in pkgs.linuxPackagesFor (pkgs.linuxManualConfig rec {
version = "${tag}-wsl";
src = applyPatches {
src = pkgs.fetchFromGitHub {
owner = "microsoft";
repo = "WSL2-Linux-Kernel";
rev = "linux-msft-wsl-${tag}";
hash = "sha256-Ogce975l7yrca047+/nm+I5Bm8EMyzd+FdszzpAQ6NM=";
};
patches = [
./wsl-kernel.diff
];
};
allowImportFromDerivation = true;
configfile = "${src}/Microsoft/config-wsl";
modDirVersion = "${tag}-microsoft-standard-WSL2";

It would be awesome to have usbip support in NixOS-WSL (see https://github.com/dorssel/usbipd-win/wiki/WSL-support).
I've only gotten so far to try the usbip command inside the VM and I'm still not clear how to get that. Loading kernel package in configuration.nix didn't seem to as we use the kernel provided by Microsoft.
Is it just a case of building our own version of the MS kernel (https://nixos.wiki/wiki/Linux_kernel) ?
When from Powershell (regular user, Windows side) running
➜ & 'C:\Program Files\usbipd-win\usbipd.exe' wsl attach --busid 3-1I'm just stuck in the
usbipd: error: WSL 'usbip' client not correctly installed. See https://github.com/dorssel/usbipd-win/wiki/WSL-support for the latest instructions.What do you say ? Can we figure this out as a Step-By-Step list maybe just to complete the instructions (saying just "on other distros") over at https://github.com/dorssel/usbipd-win/wiki/WSL-support ?
