"With all of the BSD variants available for download, it's easy to incorrectly assume all of them are pure, incompatible forks from each other. Actually, there are more shades of BSD out in the world than just separate forks. One in particular made the news a couple of weeks ago when it was commercially acquired. The BSD in question is PC-BSD. The company that bought it is iXsystems, a systems deployment and integrator firm out of San Jose that has pretty strong experience implementing *BSD, Unix and Linux systems for its customer base. So, why did the company up and buy PC-BSD?"
