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"
