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
Now we use fw0, fw1, efi, ebg0, ebg1, rootfs0 and rootfs1 partition
name.
BREAKING CHANGE: bootX partition are now named ebgX
BREAKING CHANGE: platformX partition are now named rootfsX
The generate-uki command can be used to build and sign new UKI (Unified
Kernel Image). By default all parameters are taken from bitbake but the
kernel command line and the device tree used can be customized
The devtool plugin offer a high level integration with Bitbake and
thus is under GPLv2 license.
The coreos-device script is a low level scripts that implement all
the functionality and is not under GPLv2
