1. Split these scripts into smaller distinct functional units that will

   be callable _after_ installation in 2.1's system admin tools.  This is
   almost totally revamped now.

2. Support installation from DOS partition or floppy.

3. Many stray bogons eliminated.  Perhaps a few introduced.  One more
   rev should fix this up, once I've spammed my test machine a couple of
   times.

4. Installation from CD now *really* possible.

5. Allow user to specify arbitary subdirectories for NFS mountpoints -
   UFS, NFS and CD distributions now share many common elements.
