Hello Tyler

I'm not expert in FreeBSD but maybe I can give some hints for you.

1) For setup a enviroment for build, test and debug I'm using Virtualbox 
on a Windows 10 Host. Until now FreeBSD don't have a port of the 
Virtualbox 5, so for use Hyper-V with VT-x and nested pages I need a 
Windows host. My processor is a i7-3517U. After setup Virtualbox on 
windows I create a virtual machine, download a bootonly FreeBSD ISO from 
https://www.freebsd.org/where.html and install in this virtual machine. 
I do not install ports or src because I always do a checkout from the 
svn repo. So, after install I do a checkout of the most recents sources 
from svn repo. I use this command:

# svnlite co https://svn.freebsd.org/base/head /usr/src

After, I rebuild the entire system using thre procedure that you can 
find here on topic 23.6.1:

# https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html

After the rebuild you will running the version that you checkou from 
repositoy. So I do a checkout of ports.

# svnlite co https://svn.freebsd.org/ports /usr/ports

And then I install the virtualbox guest drivers:

# cd /usr/ports/emulators/virtualbox-ose-additions/ && make install clean

So afther this I have a system with the latest versions. For do a 
partial build you can use the procedure listed here on topic 23.6.6:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html


Remember, this list of commands is not complete, it is only a partial 
list of what to do. Somo commands needs others (like install the 
virtualbox guest driver), but when doing, messages will tell you what to do.

2) About do a partial build of kernel modules you can read here the 
procedure:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html 
(topic 8.5)

  Jean Sébastien Pédron did a great job writing a article about Getting 
started with kernel projects. You can read here:

https://wiki.freebsd.org/Graphics/Getting%20started%20with%20kernel%20projects


3) About ideas for projects, what do you think about port the latest 
version of virtual box host to FreeBSD :-)?
