When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:

* Ensure libseccomp is installed before starting containerd on CentOS 8
* Simplify libseccomp install on CentOS 8
- Uses `package` module
- Replaces complex version check with 'state: latest'. The version must
be > 2.3 when using with cri-o.
- Removes unnecessary `not is_ostree` condition as CentOS 8 does not use
ostree

* Enable Kata Containers for CRI-O runtime
Kata Containers is an OCI runtime where containers are run inside
lightweight VMs. This runtime has been enabled for containerd runtime
thru the kata_containers_enabled variable. This change enables Kata
Containers to CRI-O container runtime.

After host reboot kubelet and crio goes into a loop and no container is started.
storage_driver in crio.conf overrides system defaults in etc/containers/storage.conf
/etc/containers/storage.conf is installed by package containers-common dependency
installed from cri-o (centos7) and contains "overlay".
Hosts already configured with overlay2 should be reconfigured and the
/var/lib/containers content removed.
By default do not allow "unqualified" (without a registry) images
because it is considered unsecure and subject to mitm attacks.
To enable insecure pull configure for example:
crio_registries:
- "docker.io"
- "quay.io"
* log level by default increased to 'info'
* cgroup manager by default set to 'systemd'
* stream port (used by kubelet) bound to 127.0.0.1 for security reasons
* metrics can be enabled and port specified
CI job 624031102 failed with:
fatal: [ubuntu1804]: FAILED! => {"changed": false, "msg": "Failed to download key at https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_18.04/Release.key: Request failed: <urlopen error [Errno -3] Temporary failure in name resolution>"}
Assuming its a temporary problem it should get more robust with a
couple of retries like in other roles.
