OpenBSD kernel address randomized link

Or the "kernel image" could be the linker + .o files. The bootloader would remain unchanged and load everything in RAM. Then the linker would move the .o files around and link them then execute the normal kernel code.

I think the kernel already has a linker (for modules).
And this also works for IoT devices, where the filesystem is likely RO.

DAX would be an issue though.

All that said, the solution seems so obvious that I'm sure I'm missing something critical...
