Cool, been running my home server on podman + quadlets for about two years now and picked up a couple of things in the release notes

  podman quadlet list

Added in v5.6.0, lists quadlets and their containers

  podman system migrate --migrate-db

Flag added in v5.8.0. I remember seeing the bolt db deprecation warnings in the past but there was no tool to do the migration to sqlite, now there is (or just upgrade to podman 6.0.0 and it will do it automatically)
