The same result could be achieved by doing logical volumes on top of
raid-1 which is perfectly well supported by the Debian installer. I
usually do a raid-1 boot partition and then a raid-1 on the rest of the
disk which I throw into a volume group. Then allocate /usr, /var, /home
etc from this volume group.
