Clang-6 and GNUisms.

Speed up CD/DVD-based FreeBSD

We have a special case of running FreeBSD (actually a NanoBSD) from a CD/DVD. The reason behind using a CD/DVD is to prevent manipulations. Now, after the GUI hass started, the system autologin a user and autostarts Firefox. But starting Firefox takes ~ 5 - 7 minutes, while the operating system
