 In the Containerfile, set one of those images to be the ``FROM`` value. It is recommended to end each ``RUN`` command with ``&& ostree container commit``. DNF and RPM commands can be re-enabled by using ``RUN rpm-ostree cliwrap install-to-root /`` which will translate those to rpm-ostree commands. Real-world examples of how to customize these containers with rpm-ostree can be found `here <https://github.com/coreos/layering-examples>`__.
 
+Some ``rpm-ostree`` arguments such as ``kargs`` do not work in a Containerfile. For that instance, it is recommended to use a `Kickstart file <../virtualization/virtual_machines.html#kickstart-file>`__ to provide defaults kernel boot arguments by using ``bootloader --location=mbr --boot-drive=vda --append="<KEY>=<VALUE>"``.
