Found by: michaelortmann
Patch by: michaelortmann

* enhance dragonflybsd support
* enhanced doc for dragonfly bsd
* rip out support for BSD/OS (originally called BSD/386 and sometimes known as BSDi) because Wind River discontinued sales of BSD/OS at the end of 2003, with support terminated at the end of 2004.
* added TrueOS
