I see bzImage was explicitely targeted in make invocation before. I am not too much concerned with this rename, but is it being for some specific purpose or just for cosmetic reasons?

This name change here of the kernelPath file is just to avoid a confusing/inaccurate name.
Note that bzImage is the default make target for x86 builds, but that other architectures don't necessarily have a bzImage make target. For this reason I removed bzImage as the target in the make invocation so it would fall back to building the default target which should generate a kernel image usable for most other architectures. KVM on arm64 for example needs an uncompressed vmlinux file, and vmlinux is generated by the arm64 default make target.

Thanks for the taking the time to write this down in details, much appreciated.

Looks fine in principle, just curious about the renaming part. Also leaving some more time for other eventual reviews. |
Fixes errors like these when building the kvm stage1 flavor for arm64:

Bzipped images are platform specific, so use generic names. Also, add an empty make recipe to the kernel image target to avoid using implicit rules. Signed-off-by: Geoff Levand <[email protected]>

We need to change the kernel location because in rkt/rkt#3690, the path where the kernel image was expected changed from `bzImage` to `kernel_image`.
