Erp!  I think I found it.  Your lines specifying the RAID layout are
missing some stuff.  In your "raid" lines, I think you must have
"--fstype=ext3" rather than "--fstype ext3".  This may be an issue as
the other partitions are going to be formatted (and ext3 is the default)
while /home is NOT going to be formatted.  I'm surprised it worked at
all with spaces instead of "=" in those lines.  I'd expect some errors
regarding "can't find device ext2" or "can't find device ext3" in the
other lines as well.
