- Mixing `local-path` and `distributed-path` is not allowed, doing so would cause MinIO to refuse starting the server.
- Ellipses notation (e.g. `{1...10}`) or bracket notations are fully allowed (e.g. `{a,c,f}`) to have multiple entries in one line.

> NOTE: MinIO environmental variables still take precedence over the `config.yaml` file, however `config.yaml` is preferred over MinIO internal config KV settings via `mc admin config set alias/ <sub-system>`.
