BSD 1.0 was released in 1977, which in turn built on the early Unix-releases the first of which appeared in 1971. So it took several hundreds of people working on and off for about three decades to get FreeBSD to its present state. It wouldn't take that long if one started today since nowadays there are better tools, better hardware, and a lot more knowledge about what works and what does not work. Writing a *simple* OS can easily be done by a handful of people working for a few months. Creating a "complete" OS like modern FreeBSD releases or Linux distributions or recent Windows-versions requires many man-years worth of work. Not because it is all that difficult (although some parts can be) but simply because there are so many things that need to be done. (Creating device-drivers for a gazillion different, poorly documented, hardware devices is not the least of the problems.) -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
