[OE-core] setting EXTRA_IMAGE_FEATURES explicitly in .bb file can screw things up

a while back, i whined about the inconsistent usage of
EXTRA_IMAGE_FEATURES, like this as a snippet:
meta/recipes-sato/images/core-image-sato-sdk.bb:EXTRA_IMAGE_FEATURES += "tools-debug tools-profile tools-testapps debug-tweaks"
meta/recipes-rt/images/core-image-rt-sdk.bb:EXTRA_IMAGE_FEATURES += "tools-debug tools-profile tools-testapps debug-tweaks"
meta/recipes-extended/images/core-image-lsb-sdk.bb:EXTRA_IMAGE_FEATURES = "tools-debug tools-profile tools-testapps debug-tweaks"
notice the mixing of "+=" and "=", which seems messy. then i ran
across this in core-image-lsb-sdk.bb:
IMAGE_FEATURES += "apps-console-core tools-sdk dev-pkgs ssh-server-openssh"
EXTRA_IMAGE_FEATURES = "tools-debug tools-profile tools-testapps debug-tweaks"
that *can't* be right, can it? the explicit setting of
EXTRA_IMAGE_FEATURES in that recipe file will override any such
setting in one's local.conf file, won't it? and that's how the
current manual *advises* how to add more features through your
local.conf.
i tested this target with a standard local.conf, and checked the
environment to see:
... snip ...
IMAGE_FEATURES="apps-console-core debug-tweaks tools-sdk
tools-testapps dev-pkgs tools-profile tools-debug ssh-server-openssh"
which looks fine according to the .bb file.
but if i add the following to my local.conf file (as the manual
suggests i do to add another feature):
EXTRA_IMAGE_FEATURES = "nfs-server"
i see *no* difference in the environment. hasn't the setting in the
.bb file overridden the one in my local.conf?
i *can* get nfs-server added to my list of features with
(predictably):
IMAGE_FEATURES += "nfs-server"
but that doesn't strike me as a proper solution and will certainly
come as an unpleasant surprise to someone eventually. thoughts?
