image.bbclass: image_types.bbclass is a must
The image_types.bbclass is a must since we use this in image.bbclass: [snip] python () { deps = " " + imagetypes_getdepends(d) d.appendVarFlag('do_rootfs', 'depends', deps) [snip] The imagetypes_getdepends() is defined in image_types.bbclass. Use "+=" to replace "?=" since it is a must, so that the user can use "IMAGE_CLASSES = foo.bbclass" in local.conf to add their own image class. NOTE: the IMAGE_CLASSES_append = " foo" doesn't work since we use this in image.bbclass: IMAGE_CLASSES += "image_types" inherit ${IMAGE_CLASSES} I think that it is because inherit takes effect before append? Another way to fix the problem is: IMAGE_CLASSES ?= "" inherit image_types ${IMAGE_CLASSES} But it seems that we need another name for IMAGE_CLASSES, for example IMAGE_CLASSES_EXTRA, and also need update the doc, which would make it complicated.
