Unsung Hero Of the Cloud Native Revolution: Container Linux Then And Now
summary
Walks through the lineage from CoreOS (2013) to Flatcar, Fedora CoreOS, Bottlerocket, Talos and k3OS and shows concrete engineering choices: A/B partitions with rollback derived from Chromebook roots, Ignition for early provisioning vs Cloud-init, and Gen2 overlays for reproducible builds. Calls out real failures people hit: non-deterministic package scriptlets that break upgrades, unclear reboot authority after kernel or glibc patches, and tooling gaps around systemd/dbus and kubelet integration.
