[. . . ] Configuring the Time Zone On the interactive map, you can also click on a specific city, which is marked by a yellow dot; a red X will appear indicating your selection. You can also scroll through a list and choose a time zone. The second tab allows you to specify a UTC offset. The tab displays a list of offsets to choose from, as well as an option to set daylight saving time. On both tabs, you can select System Clock uses UTC. Please select this if you know that your system is set to UTC. Tip If you wish to change your time zone configuration after you have booted your Red Hat Enterprise Linux ES system, become root and use the /usr/sbin/timeconfig command. 3. 20. Account Configuration The Account Configuration screen allows you to set your root password. Additionally, you can set up user accounts for you to log in to once the installation is complete (see Figure 3-15). 40 Chapter 3. Installing Red Hat Enterprise Linux ES Figure 3-15. Setting the Root Password Setting up a root account and password is one of the most important steps during your installation. Your root account is similar to the administrator account used on Windows NT machines. The root account is used to install packages, upgrade RPMs, and perform most system maintenance. Logging in as root gives you complete control over your system. Use the root account only for system administration. Create a non-root account for your general use and su - to root when you need to fix something quickly. These basic rules will minimize the chances of a typo or an incorrect command doing damage to your system. Tip To become root, type su - at the shell prompt in a terminal window and then press [Enter]. Then, enter the root password and press [Enter]. The installation program will prompt you to set a root password2 for your system. The installation program will not let you proceed to the next section without entering a root password. The root password must be at least six characters long; the password you type is not echoed to the screen. You must enter the password twice; if the two passwords do not match, the installation program will ask you to enter them again. 2. A root password is the administrative password for your Red Hat Enterprise Linux ES system. You should only log in as root when needed for system maintenance. [. . . ] There is no need to use a driver disk unless you need a particular device in order to install Red Hat Enterprise Linux ES. Driver disks are most often used for non-standard or very new CD-ROM drives, SCSI adapters, or NICs. These are the only devices used during the installation that might require drivers not included on the Red Hat Enterprise Linux ES CD-ROMs (or boot disk, if you created an installation boot disk to begin the install process). Note If an unsupported device is not needed to install Red Hat Enterprise Linux ES on your system, continue with the installation and add support for the new piece of hardware once the installation is complete. E. 1. 2. How Do I Obtain a Driver Disk? The Red Hat Enterprise Linux ES CD-ROM 1 includes driver disk images (images/drvnet. img -- network card drivers and images/drvblock. img -- drivers for SCSI controllers) containing many rarely used drivers.
