It is unrelated to featured. Although both returns if a given feature is enabled or not, featured uses the variations framework while libsegmentation uses a local store when enabled.

chromeos-base/feature-management-private
provide the private features definitions for chromeos-base/feature-management-data
, that build the database needed by libsegmentation
in chromeos/feature-management-data/libsegmenation_pb.h
. It also holds the protobuf that describes a feature.
chromeos-base/feature-management-bsp provide device selection override, if needed.
We can check manually if a feature is supported on the test image with
/usr/local/sbin/feature_explorer --feature_name=FeatureManagementNotSupported 0 /usr/local/sbin/feature_explorer --feature_name=FeatureManagementBasic 1
Public features are added in features.star
starlak file.
