First of all, the CD boot process doesn't pick up the boot.config. Secondly,
many motherboards use a BIOS which causes the -P test to fail.
What you can do is create boot/loader.conf on the CD image containing

Yes, it is. You don't need a login for an installation. You do need to make
sure you enable the correct serial port (usually ttyd0, as you point out)
in /etc/ttys before you reboot at the end of the installation.

at a very late stage). One day I will make time to sit down and work out how
to do it properly on a CD.
