For some background, see:
What this branch does implement a Jenkins job in CentOS CI that combines baseline Fedora 25 content with an overlay of content that auto-builds packages from git of some key projects like ostree/rpm-ostree.
The goal of the system is to be a workstation, using rpm-ostree for the base OS, and a combination of Docker and Flatpak containers, as well as virtualization tools such as Vagrant.
This project is actively maintained and is ready for use by sophisticated and interested users, but not ready for widespread promotion.
First, try out
rpm-ostree install to layer additional packages. For example,
rpm-ostree install powerline.
Next, try oc cluster up to create a local OpenShift v3 cluster.
Another good way to work is to create "pet" Docker containers, and use
inside these. You can use e.g.
-v /srv:/srv so these containers can share
content with your host (such as git repositories).
Here's a blog entry on using dnf+snapper(btrfs) for host updates. This is an implementation of client side snapshots. What makes rpm-ostree better here is that the system is composed (and ideally tested) server side.
