MacOS Tweaks For Unix Geeks

Here's a list of a few tweaks that won't interest most average users, but are useful for people accustomed to a more Unix'ish way of viewing the universe.

• Add this to /etc/hostconfig to prevent it from setting the hostname to whatever DHCP reports:

HOSTNAME=foo.bar.com

• Add this to /etc/rc.shutdown.local to prevent the startup "BONNNNNNNGG!" sound:

#!/bin/sh
/usr/sbin/nvram SystemAudioVolume=""

• Execute this command once to show interesting stuff during startup:

nvram boot-args="-v"
