I hope my first questions are not too > trivial. Manuel Kasper <mk@neon1.net> posted a 'minibsd' how-to a few weeks ago. His article is at: http://neon1.net/misc/minibsd.html Additional slashdot commentary: http://bsd.slashdot.org/article.pl?sid=03/03/18/1947230&mode=thread&tid=122 These may help you get something closer to what you want.
