Fedora CoreOS: architectural walkthrough
Fedora CoreOS is a future Fedora edition drawing from the best of Fedora Atomic Host and CoreOS Container Linux. This talk is an update from the Flock one, but will start with an overview of what Fedora CoreOS is, and how it incorporates lessons from those two operating systems into its DNA. We will then focus on the current state of Fedora CoreOS: design decisions, development, and community.

Fedora CoreOS Build Tooling
Fedora CoreOS is built, tested, and released differently than the operating systems from which it originated, Fedora Atomic Host and CoreOS Container Linux. This talk covers a very brief overview of how CL and FAH images were previously built and how the Fedora CoreOS build system, CoreOS Assembler, improves upon them. It discusses how CoreOS Assembler aims to unify the developer and production build processes and ensure reproducibility. It also covers the CoreOS Assembler developer workflow both for developing the OS and build process itself. Finally it covers what is coming next for CoreOS Assembler.

Ignition: declarative first-boot host configuration
Ignition is an early-boot node configuration tool, based on a declarative configuration format and meant to run on first boot. It is capable of partitioning disks, creating filesystems, and writing configuration entries for full initial provisioning of a Linux host.
This talk will describe design choices specific to Ignition, highlighting all the fundamental differences with traditional `cloud-init` approach. It will show how Ignition enables automated, declarative, immutable infrastructure patterns in clustered Linux deployments. Additionally it will cover Ignition architecture, internal Go patterns and initramfs integration.
