use them yet, but it's close (we're working on the last wrinkles in the CD install for now). 2. Complete the CDROM installation strategy code. 3. Simplify the distribtuion loading code. 4. General error message cleanup. 5. Write the /etc/fstab file now and split those routines into config.c 6. Clean up the menus a little more.
