One of the real downsides of ARM is, it seems, the relative lack of standardization. An x64 kernel? It’ll run on most anything from the last ten years at least. And as for boot process, it’s probably one of two options (and in many cases one computer can boot either legacy or EFI).

ARM, on the other hand…my raspberry pi collection does one thing, my Orange Pi does something else, and God help you if you want to try swapping the Orange kernel for the Raspberry (or vice versa)!
