Can a stock kernel with all the probing still intact ever perform as well as a custom one with all the non relevant stuff stripped out? Subsecond pod starting is very handy.

Thanks for sharing your experiments. Your approach to integrate Kata shows some points improve to support this use case.
I did not consider in the past use the host kernel as the kata kernel but definitely is a use case we could support.
A couple of questions related on how to mange the kernel and image when you add Fedora RPMs.
Lokesh is working on Fedora RPMs. I will leave the questions to Lokesh, except to say that reusing kernel and QEMU packages is attractive because it means fewer builds, fewer packages, and a smaller test matrix.
Are you going to add a symlink to allow the kata runtime always find the latest installed kata kernel ?
How are you planning to update the modules if a kernel changes ? The image will by generated after a new kernel update? Or every time the kernel changes you are going to update the kernel from package?
