I should smile.

In 1997 I had /dev/sda, which had SCSI target Id #3.
When I added another disk, being target #2, that became /dev/sda
And the original /dev/sda went into /dev/sdb
rendering the system _unbootable_
So after about 10 years, is the answer use UUID.

I should laugh ...

During system recovery provide the boot option:

  root=UUID=4a6aed11-42dd-4c82-81ce-8f469e93f210
