I want to learn that why I can not decompress compressed kernel image made with
make bzImage. If we look at the
vmlinuz with file, it gives following output:
$ file vmlinuz-4.0.0-1-amd64 vmlinuz-4.0.0-1-amd64: Linux kernel x86 boot executable bzImage, version 4.0.0-1-amd64 ([email protected]) #1 SMP Debian 4., RO-rootFS, swap_dev 0x3, Normal VGA
It seems it is not a regular bzip2 compressed file.
