Binary package hint: partman-base

I have a machine with 3 hard-disks, /dev/sda for / and swap and /dev/sdb and /dev/sdc for a RAID 1 /home.
This works fine in karmic, also an upgrade from Karmic to Lucid (update-manager -d) also works fine now.
However it seems feasible that you would like to overwrite / with a fresh ubuntu install and leaving the /home RAID 1 intact. One would probably use the alternate cd installer for this.
During tests, it does not seem to be possible.. I have tried leaving as much as is during the install, erasing all data from /dev/sda, recreating the RAID array but after finishing partitioning I always get:
--------------------------------------------
Failed to remove conflicting files
The installer needs to remove operating system files from the install target, but was unable to do so, The install cannot continue
--------------------------------------------

See screenshot for partitioning scheme...
