Bug 455813

SUMMARY
After adding a new disk and rebooting, the device name is changed. For example, sda would become sdb, or dasda would become dasdb.

Before kernel 5.3, devices would always be probed in the order in which they exist on the bus, resulting in the first device being named 'sda', the second device 'sdb', and so on. Controllers could be probed in parallel but the devices would still appear in the same order on a per-controller basis. If there was only one controller, they'd be predictable as long as new devices weren't added in the middle.

Begining with kernel 5.3 the order in which SCSI devices are probed and named has become non-deterministic. This is a result of a change that was submitted to add asynchronous device probing.The probing happens asynchronously on a per-device basis, so even devices on a single bus can appear in "random" order. The logic behind the change is that if you will have dozens of disks, one wants them to start as early as possible, instead of probing/failing/waiting in a synchonous way; in an environment where there are hundreds of disks, and even more partitions, this change is even more important.

The result of this is that in every boot then the local partitions, which are marked as "hidden" (as I won't ever want to unmount them) appear under Devices.

That sd** should be an IdUUID
