Where 6.0 and previous had rescue disks containing a large number of useful utilities. The 6.1 solution, to use the installation media as a rescue disk, has very few utilities. Staples like 'cp' and 'vi' are missing! Mounting the past-installed media to obtain those utilities isn't always possible, either. That's what the rescue disk is supposed to solve. (If this is to be remedied, then I might suggest that 'lilo' be included, which was absent from 6.0 also)
Improving the rescue image is currently being examined...
