I’m getting this warning when building core-image-minimal, is ok to ignore it, or should I do something to solve it?

`WARNING: core-image-minimal-1.0-r0 do_image_sdimg: MENDER_BOOT_PART_SIZE_MB is set to zero, but IMAGE_BOOT_FILES is not empty. The files are being omitted from the image.`

Hi @sd-ricardo,

You should check what is in `IMAGE_BOOT_FILES`, and how it ended up there. Are these files that your device needs to boot? Then you have to figure out where to put them, and you probably need a `/boot` partition for it. If they are not needed, then remove them.
