红帽全球峰会4.6. 配置文件覆盖部分
overrides 部分可以识别可选的 protocol 子部分，并可包含多个 protocol 子部分。系统使用强制 type 属性将路径设备与 protocol 子匹配。匹配 protocol 子部分中的属性优先于其它 overrides 部分中的属性。如果有多个匹配的 protocol 子部分，则后续条目具有更高的优先级。
protocol 子部分识别以下强制属性：
| 属性 | 描述 |
|---|---|
|
| 指定路径设备的协议字符串。可能的值包括： |
|
| |
| 此属性不是正则表达式。路径设备协议字符串必须完全匹配。 |
以下列表中的属性对于 protocol 子部分是可选的。如果没有设置它们，则应用来自 overrides, devices 或 defaults 部分中的默认值。
