# IMAGE_INSTALL triggers package builds via do_rootfs recrdeptask.
# Even for multi-layer mode, list packages here to ensure they're built.
# The PM will install them directly to layers from DEPLOY_DIR_IPK.
# Note: IMAGE_ROOTFS is still created but ignored for packages layers.

# Note: No ROOTFS_POSTPROCESS_COMMAND needed - IMAGE_ROOTFS is empty
