Testing with the latest oe-core was unable to boot and only syslinux was running. It appears that the desired kernel is not on the /boot partition, and hence the system can't continue. bzImage is installed and available, so we switch to that. We also ensure that both kernel-vmlinux and kernel-image are installed to the rootfs so we can have choices in the future. Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com>
