Delivering the OS via OCI images: Btrfs snapshots, delta updates and 3-way merges
David Cassany, Dirk Müller
Delivering a Linux OS via OCI images unifies infrastructure management but often introduces severe network and state-reconciliation bottlenecks. This talk dives into the mechanics of solving these challenges by applying OS updates directly from OCI images to btrfs snapshots. We will explore how to drastically optimize these atomic upgrades using zstd-chunked compression, enabling systems to execute file-level delta updates via HTTP range requests instead of pulling full layers. Finally, we will demonstrate how to leverage snapper for seamless 3-way merges, safely reconciling upstream OS changes with local user configurations.
