我有一个问题，无论何时重新启动磁带库，挂载磁带或任何操作，Linux正在更改磁带库的path，使其无法自动执行备份处理，甚至在磁带库上有两个驱动器时甚至更糟，因为系统更改xxx0到xxx1，反过来，当fc被拔掉，系统重启或w / e
我想知道如何在udev上进行持久化configuration，以便每次将相同path分配给基于序列号的同一个磁带设备w / e，例如，因为它永远不会更改，所以对于SN将是xxx0每次1234，5678的xxx1等，即使系统重新启动…
我使用的是基于Debian发行版的定制Linux，所以所有在Debian上运行的东西都在我的…
我希望你能帮助我，谢谢。
这是我的信息…
