Gentlemen:

   Don't shoot the messenger ....

   With the change, in 4.1, to all character
   special files, the utility/package cdrecord
   is now broke.

   Attacted is the output of a script, and the
   script itself, that I used extensively with
   2.2.8.

   I have the bad feeling that cdrecord is not
   the only utility that is now broken.

    Attacted:  cdClone -     the script that I mentioned above
               cdClone.out - the script's output under 4.1
