Now a single unified kernel image is built using a new CoreOS
specific functionality added in the efibootguard UKI stub to
automatically insert root=PARTLABEL=rootfs0 (or rootfs1) in the
kernel command line
BREAKING CHANGE: coreos-image-uki.bbclass now only generate a
single kernel image named kernel-${MACHINE}.efi
Default value related to efibootguard are not set inside the distro
and MACHINE that use coreos-image and doesn't define EFI as a
MACHINE_FEATURE doesn't get the efibootguard-tools package.
Checking for COREOS_EFI_SECUREBOOT_INSTALL_PUBKEY_IN_EFIDIR
was not done properly resulting of the key always being
installed inside the EFI partition.
We need to generate some more file to better integrate the CI system
with this repository. The new class generate a new IMAGE.ci-artifacts
file with the list of file that need to be uploaded by the CI to our
storage server. To enable this class, the CI need to add:
`COREOS_IMAGE_EXTRACLASSES += "coreos-image-ci"`
to the auto.conf configuration file inside the build directory.
