- 我有一台带有 2 个 USB 插座的小型计算机：A 和 B。
- 我想任何外部 USB 磁盘，附于插座A- 安装为“设备A“
- 我想任何外部 USB 磁盘，附于插座B- 安装为“设备B“
尤其是：
可以将任意数量的不同磁盘连接到插槽 A。它们都应作为“设备 A”安装。
由于这种情况，我无法使用磁盘的 UUID，而必须识别插槽。
我正在使用 udev 规则自动挂载磁盘。我该如何实现？
编辑：添加
$ udevadm info -a -n /dev/sda1
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
