Those should be executed offline during build, so it's only for packages you install later on. Have a look at https://github.com/koenkooi/meta-angstrom/blob/master/recipes-images/angstrom/systemd-image.bb. That recipe will not include packagemanagement and u-a if ONLINE_PACKAGE_MANAGEMENT is set to none.
