osX: File locations

• Font directories
  ~/Library/Fonts/
  Fonts stored here will be available to you only when you are logged in.
  
  /Library/Fonts/
  Fonts stored here will be available to all users of this computer. Safe to use
  
  /System/Library/Fonts/
  System fonts are stored, do not mess with this one.
  
  /Network/Library/Fonts/
  Fonts stored here will be available to all in the network if you have netinfo server running.
  
  {ClassicStartupVolume}:System Folder:Fonts:
  This is an interesting feature! Any fonts you have installed in your Classic System Fonts folder will be available to any user on your machine. This is true whether or not Classic is running! Unfortunately, most of my fonts are managed by Adobe Type Manager, which, while it works fine under Classic, does not make the fonts available to OS X applications. In addition, ATM would be required to properly render any PostScript outline fonts under Classic.
  
  
• Misc directories
  /Users/* - All user directories (probably only 1 user). All OSX specific apps I've installed seem to be very good at keeping the files they need in one directory in the user's own directory. You'll probably want to empty your trash before backing up user directories.
  
  /private/var/db/netinfo - contains the NetInfoManager config. If restoring from a backup, copy local.nibak into place and then ask NetInfoManager to 'restore from backup'. I once tried copying the running config into place and restarting, the result was a awful mess.
  
  /private/etc - unix configs that you might mess with, e.g. hostconfig, sshd keys, sendmail config?
  
  /System/Library/StartupItems/ - if you've setup ssh, sendmail or any other extra services then their startup scripts will live in this dir.
  
  /Applications/XXX - for any additional apps (XXX) that you may have installed outside of your own Applications directory.
  
  /usr/local/XXX - if you've installed some standard unix apps, they probably found their way into /usr/local (e.g X11 and Samba). Binaries often install into /usr/local/bin.
