[yocto] Basic question: "core-image-minimal" v.s "core-image-base" ?

[Jerry Lian]

Thanks for answers from Ross and Andre.
Now further question:
* If we look at file \poky\meta\recipes-core\images\core-image-minimal.bb
<http://core-image-base.bb>
========================================================
SUMMARY = "A small image just capable of allowing a device to boot."

IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL}"

IMAGE_LINGUAS = " "

LICENSE = "MIT"

inherit core-image
========================================================
* "inherit core-image" *comes after* "IMAGE_INSTALL = ..."
* Will the "IMAGE_INSTALL" in this file be overridden by "IMAGE_INSTALL" in
"core-image"

So what is the rule for "overridden"?
