Sorry I should have been more clear, I was focussed on figuring out how
to update the instructions per changes in live-build that the manual
and manpage have not kept up with, not so much the correctness of the
formatting of the preseed file content itself, which I did not expect
to likely be wrong.
Doing a little googling into this aspect, I've come across the
following format:
d-i live-installer/enable false
Note the space instead of an equals, and indeed prefixing with "d-i ".
I hope that fixes the problem for you. I'll add it to the todo list as
another fix to be made. :)
