Message:

add an option to make an “fwcf killer” image

AND NO, YOU CANNOT DO THIS IN A WAY THAT KILLS FWCF ONLY ON
FIRST BOOT, because you cannot write to squashfs, and THIS
MUST BE EXECUTED BEFORE the overlay filesystem is initialised.

Yes, this means you'll have to flash twice. But this is better
than nothing if you can't use failsafe, right?
