Docker vs. Podman: Rootless Containers and the Daemon-less Architecture
How Podman's daemon-less, fork-exec architecture differs from Docker's client-daemon model, and what that means for rootless containers in production.
Conceptual, architectural explainers - how a subsystem actually works underneath.
