DESCRIPTION:Delivering a Linux OS via OCI images unifies infrastructure man
 agement but often introduces severe network and state-reconciliation bottl
 enecks. This talk dives into the mechanics of solving these challenges by 
 applying OS updates directly from OCI images to btrfs snapshots. We will e
 xplore how to drastically optimize these atomic upgrades using zstd-chunke
 d compression\, enabling systems to execute file-level delta updates via H
 TTP range requests instead of pulling full layers. Finally\, we will demon
 strate how to leverage snapper for seamless 3-way merges\, safely reconcil
 ing upstream OS changes with local user configurations.
