Julius and I were looking at the code when we spotted the issue.

As Julius said, "just pass a boot param", is not easy on certain
machines, like phone. It is not user friendly either.
The system won't boot at all, a typical user will have to do a full
reinstall to fix the error.

Running with forced_gpt always on is not a solution either, because SD
card formatted with a plain MBR over an older image with a GPT won't
be mounted properly: that newer MBR will be ignored.
