The local directory is organized hierarchically, starting from the root, which, like a filesystem's root, is called /. However, this is not meant to suggest that there is a corresponding directory or file for each entry. Instead, the data is stored in a collection of files under /var/db/netinfo.
You can browse or modify the local directory using NetInfo Manager, which is located in /Applications/Utilities. Figure 10-4 shows NetInfo Manager displaying the properties of the mysql user.
