When creating an initramfs bundled into a kernel fitimage, the resulting
fitimage will only be placed into the deploy directory and not packaged
by the kernel recipe/class.
Changing the kernel recipe/class to produce a package with the fitimage
containing the initramfs is not possible, because build dependencies
require the kernel packages to be already build before the initramfs can
be created.
The kernel-image-fitimage-initramfs recipe solves this dependency cycle
by packaging the fitimage with the embedded initramfs from the deploy
directory and replaces the `kernel-image` and `kernel-image-fitimage`
packages from the kernel recipe/class.
This patch was on master-next for a short while, any feedback on it?
In the cover letter I stated the only downside of this solution is, that
in case of package based updating, it would require manually changing
the version of this recipe.
Is this an acceptable downside, or is there a good way to fix this?
regards,
Claudius
