Feature: The Atomic Host component `rpm-ostree` which is used for updates of the host has a new `initramfs` command.
Reason: By default, Atomic Host uses a generic initramfs built on the server side. This is distinct from a yum-based Red Hat Enterprise Linux where the initramfs is generated per-installation. However, in some situations, additional configuration or content may need to be added.
Result: Administrators of Atomic Host may use `rpm-ostree initramfs --enable` to run the underlying `dracut` program on the client machine (and all future updates).
