.The Podman v5.0 deprecations In RHEL 10.0 Beta, the following is deprecated in Podman v5.0: * The system connections and farm information stored in the `containers.conf` file are now read-only. The system connections and farm information will now be stored in the `podman.connections.json` file, managed only by Podman. Podman continues to support the old configuration options such as `[engine.service_destinations]` and the `[farms]` section. You can still add connections or farms manually if needed; however, it is not possible to delete a connection from the `containers.conf` file with the `podman system connection rm` command. * The `slirp4netns` network mode is deprecated and will be removed in a future major release of RHEL. The `pasta` network mode is the default network mode for rootless containers. * The `containernetworking-plugins` package and the CNI network stack are no longer supported. ** If you upgrade from the previous RHEL versions to RHEL 10.0 Beta or if you have a fresh installation of RHEL 10.0 Beta, the CNI is no longer available. As a result, you have to run the `podman rmi --all --force` command to remove all images and containers that are using those images. ** If present, the `cni` value in the containers.conf file for the `network_backend` option must be changed to `netavark` or can be unset.
