Coincidentally, I just did that today. :-)

Not a lot. If you haven't changed /etc/ttys, mergemaster will take care of it
for you. I always change this file, to mark the console as insecure (meaning
you have to give the root password to log into single user mode).

Note that this change only affects the dialup lines. On my machines I always
disable them.

Go to the following URI: 
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/i386/conf/GENERIC?only_with_tag=RELENG_8_0_0_RELEASE

Click on 'download' to get the file, or select it for a diff between another
version.

This file contains variables that will be used during a system build from
source. The main use is to have the system skip building things you don't
need.  E.g. if you don't have bluetooth devices in your server, you can set
WITHOUT_BLUETOOTH=yes in /etc/src.conf, and the system will not build kernel
modules and programs that relate to bluetooth. See src.conf(5) for a complete
list of settings (with explanations) you can apply in this file.

I tend to disable everything I don't need, because bugs and vulnerabilities in
things that are not built and installed cannot harm me. And it cuts down on
build time as well. I tend to build my own kernel for mostly the same reasons.
