Very odd Linux distro if I do say so myself. Can't get past the "partition" stage. No option taken seems to accomplish anything except running in circles. The end result (on two identical machines) is "error while initializing physical volume" or "no root files have been created". Isn't that the whole point of this stage is for Debian to write these files to the disk in order for them to be created? Selecting "Use entire disk" is pretty much meaningless, as it opts not to actually do this and write any data to the Raid system.
