That explains it - I do use update build, but on occasion, when
something fails, I tend to remove the destdir and|or obj. In this case
I started afresh a little earlier than the abovementioned commit.

BTW my next question was to be 'Why live image is only MBR, as the
install image is GPT?', but I see I am late for it...
