OSTree has built in support for updating the kernel at "runtime".  The fact
that it does so atomically in concert with the rest of userspace is an
important aspect of how it works.

Systems (by default) have two kernels and two userspaces which share storage;
if both userspace trees reference the same kernel, the storage isn't duplicated.

There appears to be some confusion here - Atomic/rpm-ostree is
definitely capable of incremental upgrades that install a new kernel
at "runtime", there's no "whole image to be respun".

The tree is currently composed on a build server, not on the client,
and it is a fresh installroot every time, but clients only download
objects which have changed.

Mainly Ansible...Chef and Puppet both require agents.
