This will definitely work, but it's not really even necessary. Just have some pre-connect script, that checks if the host is already "configured", and if not, then one-shot some Ansible playbook (or bash even) that installs what's needed. Use /tmp if root is not available. Also works for Kubernetes, though there we have better options.
