As you said, it is able to identify a disk at the expense of checking cost. However to introduce "alias" is an advantage of reducing both the cost and the risk of miss-communication, and it can easily identify it. And also, currently, kernel log and command output do not accord with the device name which a user uses (e.g. by-id, by-uuid). I would try to solve those mismatches using "alias". In other words, I'd like to introduce aliases for integrating the name of devices to control and record. Of course I will modify commands using a device name to use a persistent device names.
