       The `udevCheckHook` derivation adds `udevCheckPhase` to the [`preInstallCheckHooks`](#ssec-installCheck-phase),

     

       4
       +
       which finds all udev rules in all outputs and verifies them using `udevadm verify --resolve-names=never --no-style`.

     

       5
       +
       It should be used in any package that has udev rules outputs to ensure the rules are and stay valid.

     

       6
       +
       

     

       7
       +
       The hook runs in `installCheckPhase`, requiring `doInstallCheck` is enabled for the hook to take effect:

     

       8
       +
       ```nix

     

       9
       +
       {

     

       10
       +
         lib,

     

       11
       +
         stdenv,

     

       12
       +
         udevCheckHook,

     

       13
       +
       # ...

     

       14
       +
       }:

     

       15
       +
       

     

       16
       +
       stdenv.mkDerivation (finalAttrs: {

     

       17
       +
         # ...

     

       18
       +
       

     

       19
       +
         nativeInstallCheckInputs = [

     

       20
       +
           udevCheckHook

     

       21
       +
         ];

     

       22
       +
         doInstallCheck = true;

     

       23
       +
       

     

       24
       +
         # ...

     

       25
       +
       })

     

       26
       +
       ```

     

       27
       +
       Note that for [`buildPythonPackage`](#buildpythonpackage-function) and [`buildPythonApplication`](#buildpythonapplication-function), `doInstallCheck` is enabled by default.

     

       28
       +
       

     

       29
       +
       All outputs are scanned for their `/{etc,lib}/udev/rules.d` paths.

     

       30
       +
       If no rule output is found, the hook is basically a no-op.

     

       31
       +
       

     

       32
       +
       The `udevCheckHook` adds a dependency on `systemdMinimal`.

     

       33
       +
       It is internally guarded behind `hostPlatform` supporting udev and `buildPlatform` being able to execute `udevadm`.

     

       34
       +
       The hook does not need explicit platform checks in the places where it is used.

     

       35
       +
       

     

       36
       +
       The hook can be disabled using `dontUdevCheck`, which is necessary if you want to run some different task in `installCheckPhase` on a package with broken udev rule outputs.
