ADDITIONAL OS VERSION INFORMATION :
Ok, this is really for FreeBSD.  I lied in picking Linux, but this page would only let me get here if I lied, and yet the system ITSELF told me to report this here, and I know that the FreeBSD is a real (albiet still under development) version.

So here I am.

Anyway, it's FreeBSD 4.9-STABLE.
