Things look quiet here. But I've been doing a lot of blogging at dan.langille.org because I prefer WordPress now. Not all my posts there are FreeBSD related. I am in the midst of migrating The FreeBSD Diary over to WordPress (and you can read about that here). Once the migration is completed, I'll move the FreeBSD posts into the new FreeBSD Diary website.

This section tells you where to find out about the various kernel configuration options.
LINT
All of the kernel configuration options are documented in /usr/src/sys/i386/conf/LINT.   For example, if you open this file and search for ipfilter and you will find: 
# IPFILTER enables Darren Reed's ipfilter package.
# IPFILTER_LOG enables ipfilter's logging.

and a little below that:

options         IPFILTER                #kernel ipfilter support
options         IPFILTER_LOG            #ipfilter logging

For our example, if you need to add support for ipfilter, you would add the following line to your kernel configuration file:

options         IPFILTER                #kernel ipfilter support

To build your new kernel, you should follow the instructions for Building and Installing a Custom Kernel.
