I have noticed that in the newer versions of list-harddrives-stub (anaconda version 13.21.149-1.el6 and as recent as at least 16.25.fc16) it is listing CD/DVD ROM drives if there are disks in them, and md devices. This is different than in the past(anaconda version 220.127.116.11-1). I have done some googling to see if this was an intended change, but did not find anything. I saw where there were updates to remove partitions from the output and this appears to be caused by the same changes that added the partition output. (I think around this time frame https://bugzilla.redhat.com/show_bug.cgi?id=654436)
Is this additional output an intended change?
