红帽全球峰会第 6 章 转换回滚
Convert2RHEL 工具在以下情况下提供有限的回滚功能：
-
如果
Convert2RHEL已在 analyze 模式下运行，则工具会回滚它所做的所有更改。 如果工具失败或者被用户停止，则只有
Convert2RHEL开始使用 RHEL 软件包替换原始发行版本中的软件包之前执行的更改才可以被恢复。此时会显示相应的警告信息：The tool allows rollback of any action until this point. By continuing all further changes on the system will need to be reverted manually by the user, if necessary.接下来会询问您是否希望继续这个过程。
注意如果将
-y选项与convert2rhel命令一起使用，则跳过指示自动回滚不再可能的时刻的问题。
警告
如果在 Convert2RHEL 已开始软件包替换阶段后，转换过程被取消了或失败了，则系统可能会无法正常工作。在这种情况下，需要手动修复。请联络红帽咨询服务以获得帮助。
