### Notes & Tips:

- **Ubuntu Version**: Ubuntu 22.04 LTS is recommended. UniFi OS might not behave as expected on older versions due to dependency mismatches or outdated container runtimes.
- **Podman vs Docker**: Ubiquiti officially supports Podman for UniFi OS Server as it does not require a daemon and better supports rootless containers. This script installs it system-wide for root.
- **Firewall**: Make sure required ports are open (`8443`, `443`, `8080`, `3478/UDP`, etc.).
- **Persistence**: Depending on the deployment type, you may need to manage container data volumes and systemd integration yourself if not handled automatically by the script.
