When I create kernel contributions, I usually rely on a specific hardware, which makes using a system on which I need to deploy kernels too complicated or time-consuming to be worth it. Yes, I'm an idiot that hacks the kernel directly on their main machine, though in my defense, I usually just need to compile drivers rather than full kernels.
But sometimes I work on a part of the kernel that can't be easily swapped out, like the USB sub-system . In which case I need to test out full kernels.
I usually prefer compiling full kernels as RPMs, on my Fedora system as it makes it easier to remove old test versions and clearly tag more information in the changelog or version numbers if I need to.
