What does BSD mean?
It stands for something in a secret language that only members can know. It does not translate literally but its ok to tell you that BSD's translation is something between, ``Formula-1 Racing Team'', ``Penguins are tasty snacks'', and ``We have a better sense of humor than Linux''. :-)
Seriously, BSD is an acronym for ``Berkeley Software Distribution'', which is the name the Berkeley CSRG (Computer Systems Research Group) chose for their Unix distribution way back when.
