I do not understand also but it is the reality. Is forgotten somewhere an 
argument such "-y" ?

I precise that the problem is not that I loss my files in the partition
even some packages know how to preserve, upgrade or include them. The warnings 
of d-i or partman are well understandable.

The real bug for me is that, being not forbidden on an old installation, the 
installation freezes, waiting infinitively an answer from the user that he 
can not do !

So I think that the bug is from d-i. You must choose : Or give the user the 
ability to answer to the questions, or let dpkg/apt-get to reconfigure with the 
defaults settings of the packages such "-y" as parameters of apt-get.

I do not think that partman is relevant. Forbidden an upgrade of an old 
installation is not a good choice for me.
