How to create a FreeBSD 8.0 boot CD without boot.flp?

What I am trying to do is basically to install FreeBSD 8.0 on a CD. I 
followed these instructions to install FreeBSD on a USB stick:

minus the fdisk/bsdlabel/newfs part . I just set up rc.conf to configure 
the ethernet interface with DHCP and load sshd

then I am now creating an iso image with the boot image. So at the root 
of the CD I will have the boot directory containing the kernel subdirectory.

I figured out about the boot image error from mkisofs. I had to copy 
cdboot into the actual boot directory for the image and the path 
specified by the -b option is relative to the root directory of the CD...

So should this work according to you?
