NixOS `<nixos-hardware/microsoft/surface/surface-pro-intel>` does not function on surface pro 7 by default

[fdgefgd]

I install and then boot up a new instance of nixOS, and wish to add the proper firmware for my hardware (surface pro 7, 8GB RAM, 256GB Storage). I did the following steps:

1. Use and update the nixOS-hardware channel
2. Paste <nixos-hardware/microsoft/surface/surface-pro-intel> into my imports section
3. Enter the command sudo nixos-rebuild switch

Nothing else has been done to the install, I have just installed the system 30 minutes ago.

It fails to build, and returns the error:

error: builder for '/nix/store/0r52xqjn7qv8qc7xx3004qrp7bz8d17c-linux-config-6.0.17.drv' failed with exit code 1
error: 1 dependencies of derivation '/nix/store/hbs2d7kq010n0j00jrijxwiirh936z85-linux-6.0.17.drv' failed to build

I can provide additional information if needed. How can I fix this issue and get the correct surface pro firmware and kernel to function on my nixos installation?

I have fixed this specific error by putting microsoft-surface.kernelVersion = "6.1.18"; into my config file. Can we please make this default to avoid the same error in the future, and also add the newest kernel version as well.

Now I am getting a different error:

It seems that nixOS is trying to call the iptsd service but is unable to do so due to it not existing. Looking at my directories, there is no /ipts at all in my /dev. I am unable to fix this issue.

[fdgefgd]

I have also tried installing IPTSD through nixOS configuration.

environment.systemPackages = [
    pkgs.iptsd
  ];

It has no effect when I rebuild, but the iptsd command becomes available now. I get the same error if I were to just run iptsd in the command line normally though. Yet it does not seem to import the other 3 commands for some reason? iptsd-find-service iptsd-find-hidraw iptsd-check-device do not become available after installing this package, but iptsd does? Not sure why this is considering they are all listed in the package in the repos.

is this still happening or can this issue be closed?
