For new users, installing Ubuntu is the beginning of a new and highly
rewarding journey on the path to learning Linux. For Ubuntu system
administrators, the tasks ahead are to fine-tune the installation and to
customize the server or user environment.
NOTE
Now that you have completed the primary task of installing Ubuntu, you
can begin to customize your new operating system. This chapter looks at
getting up and running with Ubuntu. Chapter 3, “Working with GNOME,”
gives you a tour around the desktop. Next, this chapter describes some
basic administration tasks. By the end of this chapter, you should feel
