>Description:
I created an custom install disk which installs without any interaction. You do NOT want to boot this by error on a wrong machine.
So I wanted to
- turn off the 10 secs countdown to autoboot (easily done with autoboot_delay=NO)
- display a big fat warning message stating that this disk may shoot into your foot

Additionaly I wanted a simple possibility to boot with console=comconsole.

So I added:

- you may specify  beastie_message="something" e.g. in loader.conf
If this environment variable is defined, the text "Welcome to FreeBSD!" is displayed 2 lines up then the usual place leading to 2 lines room for an message.

The text in the environment variable is displayed between the greeting and the menue.

e.g. beastie_message="ESC[1;7mATTENTION! This CD will format disks andESC[7;4Hinstall without further interaction!ESC[1;0m" 

- you may specify beastie_offerserial=YES
If you do so, you get an additional menue entry which sets console=comconsole and boots.
