I've been trying to find a good, accurate, succinct definition of the relationship for some time. I'm still working on it. The best I can see at the moment is that BSD is one of the UNIX family, maybe a disowned son :-) > By definition, it certainly can't be called a clone, if certain > components are missing. I don't agree with that. Linux was called a clone long before it offered all the features of UNIX System V. > Be-that-as-it-may, IMHO BSD appears to have evolved to the point of > offering the majority of the "key" functionality that Unix offers, > which are so appealing and necessary in this day-and-age. It's more the other way round: BSD has typically had more features than System V. It's only since the introduction of System V.4 (admittedly a long time ago now) that System V caught up--by incorporating all the BSD code. > It's a bit like the early '80s with PC-DOS w/ Basic A and MSDOS w/o > -- not quite compatible, but almost ;) Well, I don't think the comparison quite fits.
