I would like to know the difference between a normal ELF executable and a kernel image. Of course I know that the ELF file format contains pointers and different sections and a kernel file should be rather a binary image only, but how are both related to each other? Both, ELF and kernel image, are output by gcc, how do I convert an ELF binary to a kernel image?
