howto sidestep sysinstall during installation

Hi all:

Is there a way to sidestep the sysinstall during the
installation process, beyond selecting the 'location' ?

i'm using FreeBSD 8.0 200905 i386 snapshot DVD and looking
for an approach to drive the entire installation from the
Fixit# command line console.

i'm a experienced Gentoo Linux user.

Any suggestions, pointers or observations ?


thanks
Saifi.
