Hello! I was reading on the forum that in the past people have tried to use Raspberry Pi secure boot to implement signed images on their boot alongside mender. Additionally, looking over the documentation for mender it says that this is a possibility and mender does not explicitly support this. Is there any direction I should be looking in to find out a way to implement this into my system, or extend the recipes for mender to sign my boot partition? I was looking at the MENDER_IMAGE_BOOTLOADER_FILE variable with not much success.
