1. Installation

The Red Hat Enterprise Linux installer (also known as Anaconda) assists in the installation of Red Hat Enterprise Linux 5. The Red Hat Enterprise Linux 5.7 includes the following enhancements:
  • A kickstart installation, by default, has the SSH port open in the firewall settings. In Red Hat Enterprise Linux 5.7, the new --no-ssh kickstart option for the firewall command can be used to ensure that SSH access to a system is disabled.
  • The new blacklist functionality in Anaconda is used to avoid the installation or probing of drivers.
  • Anaconda provides added support for the subscription and entitlement changes implemented in Red Hat Enterprise Linux 5.7. Refer to Section 2, “Red Hat Subscription Manager and the Subscription Service” for further information.
