At "aptitude install" time ? How (didn't find any mention of debconf or 
priority in aptitude(8) ?

Yes but it's post-installation configuration (same goes for 
dpkg-reconfigure --priority=low mdadm).

Where did you get those logs ? Took longer on my box. And it depends on 
the number of kernel
installed.

Mostly Agreeded.

"failed (no arrays found in config file or automatically)." show up in 
red in my xterm... which usually means something should be fixed.

>>Maybe asking the user if he wants to build/start any array might help.
