Advanced Ignition: Live PXE and Chaining Configs

on YouTube ↗49m

" summary

Explains how Fedora CoreOS boots via live PXE with Ignition runs in initramfs to fetch JSON configs, demoing kernel args, DHCP fetch, and a local web-served config; shows Ignition partitioning a disk, creates partition and XFS var and reuses it across reboots while the rest stays ephemeral in RAM. Covers RPM-OSTree, Zincati, and constraints: live mode disables automatic OS updates so OpenShift MCO compatibility is limited, and config chaining to bypass userdata limits is available.
