Hi, all:
I have a basic question: how to tell the difference between
"core-image-minimal" and "core-image-base"?
* If we look at file* \poky\meta\recipes-core\images\core-image-base.bb
<http://core-image-base.bb>*
============================================================
=======================
SUMMARY = "A console-only image that fully supports the target device
hardware."
IMAGE_FEATURES += "splash"
LICENSE = "MIT"
inherit core-image
============================================================
=======================
* how can we tell that "core-image-base" will include "support for a
variety of hardware such as WIFI, bluetooth...", as compare to
"core-image-minimal"?
* Do I miss any other document that I need to read?
Thanks!

"diff" is your friend. You'll see that core-image-minimal explicitly sets
IMAGE_INSTALL, which is otherwise set by core-image to respect
IMAGE_FEATURES and other variables.

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"?

core-image-base takes the default value of IMAGE_INSTALL from
meta/classes/core-image.bbclass, but core-image-minimal over-rides the
default value and effectively removes packagegroup-base-extended.
See meta/recipes-core/packagegroups/packagegroup-base.bb for more
details of what gets pulled in by packagegroup-base-extended.
