Thanks for sharing you configuration.  I think I got podman working with
the following system services:

```scheme
      (simple-service 'subugid-config etc-service-type
                      `(("subuid" ,(plain-file "subuid" 
"plattfot:100000:65536\n"))
                        ("subgid" ,(plain-file "subgid" 
"plattfot:100000:65536\n"))))
      (simple-service 'containers etc-service-type
                      `(("containers/storage.conf" ,(plain-file 
"containers-storage.conf"
                                                                "\
[storage]
driver = \"btrfs\"
"))
                        ("containers/policy.json" ,(plain-file "policy.json"
                                                               "\
{
    \"default\": [
        {
            \"type\": \"insecureAcceptAnything\"
        }
    ],
    \"transports\":
    {
        \"docker-daemon\":
        {
            \"\": [{\"type\":\"insecureAcceptAnything\"}]
        }
    }
}
"))
                        ("containers/registries.conf" ,(plain-file 
"registries.conf"
                                                                "\
unqualified-search-registries = ['quay.io', 'docker.io']
[[registry]]
location='localhost:5000'
insecure=true
"))))
```

The hello-world from docker.io works, the one from quay.io does not.
But might be an issue on their side.

I got further with distrobox now when podman seems to be correctly
setup.

```
guix shell distrobox -- distrobox create -i docker.io/library/ubuntu:22.04
```

Works, but I cannot enter the container:

```
$ guix shell distrobox conmon runc -- distrobox enter ubuntu-22-04
Container ubuntu-22-04 is not running.
Starting container ubuntu-22-04
run this command to follow along:

 /gnu/store/yph7wgfp922w7ck6pclgq10mcg7j5gxi-podman-4.4.1/bin/podman logs -f

```

Looks like there are some missing OCI binaries, I used `--verbose` and
rerun it and saw this in the output:

So I'll keep digging when I have time.
