[oe] copy combined kernel+initramfs into main image

[André Draszik]

Hi,

I have a need to copy my bundled initramfs+kernel image into the main
filesystem image. So far I have failed miserably...

I have tried to achieve this by:
1) adding a new kernel PACKAGE and adding the bundled image file to it
2) moving the 'bundle_initramfs' task in kernel.bbclass before do_package
(rather than before do_deploy)

1) on its own is not helpful, because do_bundle_initramfs hasn't run yet,
i.e. the resulting package will be empty.
2) causes a recursive dependency, basically
kernel:do_bundle_initramfs -> initramfs:do_image_complete ->
initramfs:do_rootfs -> kernel:do_packagedata
I think because of do_rootfs[recrdeptask] += "do_packagedata" in
image.bbclass:


Now I can't figure out why the kernel's do_packagedata ends up in my chain,
I am not adding any kernel modules to the initramfs image.

Is there a way to break this loop? Or explicitly remove the
kernel:do_packagedata from my initramfs recrdeptasks? So that I can end up
with a non-empty a kernel-image-bundled-initramfs PACKAGE?


More generally, is there a way to achieve what I want? Maybe in a different
way?



Thanks.
Andre'


PS: I could probably do a two-staged approach, build the bundled initramfs
first, and then manually copy it from DEPLOYDIR during rootfs creation time
of the main image. But that seems cumbersome and I was hoping for a neater
solution :-)
