I posted this in part to raise the issue of the Fedora 26 builder
not being available yet, but I disagree on the fact that we can't
get rid of Fedora 23 and 24 until that's in place. Building on
two unsupported Fedora releases doesn't really buy us anything
except for more load on the already tightly packed CI hosts.

I've been working on Ansible playbooks for my development machines
and I've intended from the very beginning to make them generic
enough that I could use them for my own builders too with only
minimal changes.

Since I'm going to spend time on that regardless, I'm perfectly
fine with coming up with something that can turn a freshly-installed
Fedora guest into a builder suitable for the CentOS CI.

As for the installation step, I've never used kickstart but I was
thinking of taking advantage of the amazing work the virt-builder
maintainers have been doing in quickly preparing templates after
a new Fedora version has been released.

How does that sound?
