This document discusses Conair, a Docker implementation that uses systemd for container management and Btrfs for snapshots. It advocates for using fewer configurations and more conventions. Key aspects include using Archlinux as a base image, systemd-networkd for networking, and Btrfs subvolumes and snapshots to manage container images. Conair provides commands like "conair init" to set up the environment and "conair run" and others to manage containers, taking advantage of systemd integration while running multiple services within a single container.
