If you find yourself in this position ever, do yourself a favor and try to avoid this immediate "jump to make it as close to Linux as possible". I know several people who've had this opinion (being hardcore Linux users) and of those, a few have moved over to OS X (one kicking and screaming, no less). The rush to "just make it look like Linux" is unneeded and probably counterproductive. OS X is a terrible Linux machine, but it's an outstanding BSD machine. Rather than try to force it into what you know, give yourself a short time to get comfortable with the Linmux->BSD shift and you'll find very little need to beat OS X into submission.
