Then make the ISO, as described in the Making an Installation Boot CD-ROM section of the Red Hat
Enterprise Linux 3 Installation Guide. Or by issuing the command:
mkisofs -o file.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-tab
Note that
is the relative path to the directory containing the isolinux files you got from
isolinux/
the distribution cd, while
You may then burn the ISO to CD-ROM. To use the disc (assuming you left the label for the kickstart
boot as 'ks'), you should boot and type "ks" at the prompt. When you hit enter, the kickstart should
begin.
4.4.10.10. Integrating Kickstart with PXE
In addition to CD-ROM-based installs, RHN supports kickstarts through a Pre-Boot Execution Envi-
ronment (PXE). This is less error prone than CDs, enables kickstarting from bare metal, and integrates
with existing PXE/DHCP environments.
To use this method, you should make sure your systems have network interface cards (NIC) that sup-
port PXE, install and configure a PXE server, ensure DHCP is running, and then place the appropriate
files on an HTTP server for deployment. Once the kickstart profile has been created, you may use the
URL from the Kickstart Details page, just as you do for CD-ROM-based installs.
To obtain specific instructions for conducting PXE kickstarts, refer to the PXE Network Installations
chapter of the Red Hat Enterprise Linux 3 System Administration Guide.
Tip
Upon running the Network Booting Tool as described in the Red Hat Enterprise Linux 3: System
Administration Guide, ensure you select "HTTP" as the protocol and include the domain name of the
RHN Satellite Server in the Server field if you intend to use it to distribute the installation files.
4.5. Errata
If you click the Errata tab on the top navigation bar, the Errata category and links appear. The pages
in the Errata category allow you to track and manage Errata Updates.
Tip
If you want to receive an email when Errata Alerts are issued for your system, go to Your RHN =>
Your Preferences and select Receive email notifications.
Red Hat releases Errata Alerts in three categories, or types: Security Alerts, Bug Fix Alerts, and
Enhancement Alerts. Each Errata Alert is comprised of a summary of the problem and the solution,
including the RPM packages required to fix the problem.
Icons are used to identify the three types of Errata Alerts:
— Security Updates available, update strongly recommended
