Well! This explains some odd behaviour I've seen on some servers that were wiped and reinstalled frequently, often with differing legacy BIOS vs UEFI vs GPT vs MBR settings.
I had a `dd if=/dev/zero of=/dev/sda bs=1k count=1000` or similar to wipe the disk just enough that the provisioning would be happy... Or, at least, it was happy most of the time.
I bet this was my root cause!
