I love containers, it's really cool technology to preserve and distribute environments. To manage containers I prefer podman and its friends buildah and skopeo. podman 4 introduced many cool features but it's unavailable in Ubuntu 22.04 which is my primary OS, the latest version there is 3.4.4. Thus, I decided to backport podman from Debian Testing where it's already packaged by mighty Debian maintainers.
