The identifiers are structured data, they're not visible unless you go
looking for them.

I'm open to other suggestions on how we can positively identify storage
devices over time, across reboots, replacement, and dynamic reconfiguration.

My home system has 4 disks, 2 are identical except for serial number.
Even with this simple configuration, it's not trivial to identify which
message goes with which disk across reboots.
