Mmm, who is the maintainer of partitioner, and why does a fixed version
not get uploaded ? is there a source apt repository for the udebs we
use, and can we look at them with apt-cache ?

Nope, i think it was both. autopartkit ate my partition table, and
partconf began formating my first partition, thus erasing all my boot

because the display was hosed, and i had only a black screen to look at ?
Because partconf and autopartkit only offered the continue button and no
abort or something such ? I don't remember exactly, and i can't really
retry it, since i lost everything that was on the disk, including the
d-i initrd.

About the warning, every disk touching program issue such warning, user
mostly have come to ignore them. But autopartkit is potentially more
dangerous, and should have a more flashy warning than the usual "this
will erase all data" one.

And maybe someway to detect that the harddisk is already partitioned,
and not offering autopartkit by default in this case.
