Indeed, I stop at the same spot, before actually creating the image
and/or the modules. Therefore I'm missing the Module.symvers which
usually is of no harm, in fact technically it turned out here to be a
But politically this is a bug nonetheless, the symbols are not

I honestly don't know whether it will fail, taint or whatever. From a
license POV contrary to common belief (!but! IANAL) it *is* possible
to link non-GPL and GPL, just that the product is non-distributable,
e.g. an end user is allowed to link any non-GPL bits using kernel
headers. The kernel module check mechanisms can't judge on whether
this kernel & kernel modules is going to be redistributed, so it
But that's all academic, perhaps trying out the packages will show
whether it fails, taints or remains silent. :)
