Actually you can have multiple slices on a dangerously dedicated disk.
Try the following:

do a dangerously dedicated install onto a small disk.

then do a dd to copy the small disk to a bigger one.

boot off the new disk and run sysinstall. Go into Fdisk, you will see
that there is free space. Create a new slice, and then lable it, and
create a file system. Worked fine for me when I tested it to see what
would happen.
