Prevent zImage to be copied to /boot/ in image

Prevent zImage to be copied to /boot/ in image

[Christophe Aeschlimann]

Hi,

I'm using the danny branch and I would like to know if there is a way to
not have the zImage included in the generated image under the /boot/ folder.

I'm trying to save on space in the generated image and I couldn't find
anywhere to configure that behaviour.

Thank you,

Have you tried clearing this variable:

(from kernel.bbclass)

# Allow machines to override this dependency if kernel image files are
# not wanted in images as standard
RDEPENDS_kernel-base ?= "kernel-image"

Cheers,

Thank you for your answer,

I did that but it still didn't work.

I now found out that it is because I have an out-of-tree kernel module
in my layer that inherits module.bbclass.

And module.bbclass does the following :

RDEPENDS += "kernel-image update-modules"

Is there a reason why module.bbclass requires kernel-image ?

Best regards,

It shouldn't be required, the image isn't used by the modules at
runtime. In fact, I can see that we've removed the dependency in
master (along with other module build reorganizations).
