I have been playing about with BSD 10.1 in VirtualBox (one of the items on my bucket list to understand how to manually partition a drive using BSD terminology). I am, by the way, enjoying it and am quite impressed with the quality of the BSD Handbook.
I did not specify to install kernel sources during the initial load and am now regretting it. I would like to do so in order to get VB Guest Additions working.
I've found two links that seemed useful, but neither one helped at all:
This one was eight years old:
http://www.cyberciti.biz/faq/freebsd...l-source-code/
The other one referenced BSD v. 9.1 very specifically.
Would someone be so kind to point me in a useful direction?
