> more than one target service of type 'account'

I did not add any new service, I just modified openssh-service-type.

```
(operating-system
    (inherit os)
    (services
     (modify-services
         (operating-system-services os)
         (openssh-service-type
          config =>
          (openssh-configuration
           (inherit config)
           (permit-root-login 'without-password))))))
```

Full system description in attachment.

I think it's becaused you used operating-system-services instead of
operating-system-user-services; could you try again with the later?

Thanks,
