They differ only on that the latter has CONFIG_LOCALVERSION added. Is this normal? Can I depend on the copy in STAGING_KERNEL_DIR? I think that is what the configure script is currently using. How else might it differ? >> What is the correct way to record the dependency in the recipe? >> >> Why isn't this done in module.bbclass?
