 The problem is solved for i386 style CDs w/o md root image - if / is a
 cd9660 filesystem, sysinst just used the already mounted CD.
 
 But amd64 still uses md on /.

 I'd rather avoid such magic and probe the device for media being present
 (i.e. make sysinst gracefully deal with a wrong selection instead of mount
 failing).
