Er, right.

Even SCSI ID would be an improvement! This is exposed via sysfs,
though not wonderfully. Use the device path followed by block/. But
that has plenty of failure modes too.

The device nodes wouldn't be right. The original failure was trying to
create /dev/sdb2, when there no longer was such a device (it only had
one partition).
