OK I understand that.
But I have a problem in partionning:
It's a new (for me) tool : partman and I can't find how to create a PReP boot
partition with it. (There's no choice for it nor an obvious way to force code
x41).
I tried whith a "do not use" but this did not triggered the installer .
I'm thinking of creating a new iso image with an "old" cfdisk on it and
partitionning in the shell if possible.
