This page is intended to list the major changes I make to a vanilla install
of FreeBSD. Some are just preferences, but the majority are for security.
It shouldn't be considered any sort of comprehensive "locking down FreeBSD"
guide; it's really just a collection of notes for myself that I thought
might be useful to others too.

My use case is for a server, but a lot of the changes would be useful for
a desktop user as well. Each section will have an explanation of why I'm
suggesting the change, or at least some background information about it.
