What is the use case? How does this relate to kas/opt/kernelci.yml?

Do we always need to build and deploy those extra images?

KERNEL_NAME = "", that will also disable the now pointless build of the
kernel.

When is this useful? And will a normal user of isar-cip-core have that
use case as well so that we should expose it here?

This is not related kas/opt/kernelci.yml. This will be used to create rootfs for CIP/LAVA testing. 
The current recipe creates an image containing the kernel binary. Kernel binaries are not needed in
rootfs for kernel testing. Therefore, we have added an option to remove it.
This is also useful because some users may need rootfs without kernel binaries.

It will not be necessary every time.
It will need to be built when LTP is updated or when a point release is had in Debian.
The current gitlab pipeline is not that well thought out and I think it needs to be considered.

This is simpler and better.

This is intended to be used to create rootfs images that do not include the kernel.
For example, testing the kernel does not require the rootfs to include the kernel.
Since the kernel is not included, the rootfs size will also be smaller.

For my understanding: When is kernelci.yml used, when the kernel-free
image? For kernelci, we also deploy (not right now as upstream's API is
changing), but that was always with the kernel - why there?

If we do not pick up the artifacts automatically from a pipeline build,
we can make these variants also manually triggered. But I still need to
understand the apparent overlap with the kernelci builds (which happen
unconditionally so far).

BTW, where is the riscv64 variant?

I am not exactly sure about kernelci.yml, Arisu, could you explain it?
As far as I can confirm, the current gitlab CI adds getty , ssh and dmesg settings to the rootfs with minimal functionality.

For kernel-free image, I am thinking that the kernel-free image is used for kernel testing by gitlab for CIP/LAVA. 
Of course, they can also be used for other kernel tests. It may be possible to make kernelci the same.

I think that this would depend on the user and the designers of the testing tools.
Some people don't mind using rootfs with an unrelated kernel for testing.
Also, the size of the rootfs will be smaller since it does not contain kernel binaries or drivers.

I have summarized the differences:

- kernelci:
  - not include test (LTP and others)
    kenrelci probably downloads the test binaries when it runs the tests due to LAVA functionality.
  - includes dedicated scripts (ssh, getty and others) and configuration
  - include kernel binaries when built

- no_kenrel (latest patch):
  - nncludes LTP and other testing tools.
  - not included kernel binaries

If kernelci does not use the kernel contained in the rootfs, I believe it is possible to create a common image
that does not contain kernel binaries and test binaries. As for LTP and other test binaries, the same functionality
as kernelci would need to be modified to be available in CIP/LAVA YAML.

Ah, I forgot about that. I'll add it with update patch.
