Preparing a TFTP Server for Network Boot and Installation

The first step is to prepare a TFTP server on a host computer. This requires that you create the
expected directory structure for boot images and installation files. It also requires that you
configure the TFTP server as described in the following sections.
Creating /tftpboot Directory and Copy Target Files
To create the expected directory structure and to copy the required files, proceed as follows:
1. Create a /tftpboot directory, if it does not already exist on the host.
2. Copy or move the installation files (kernel, ramdisk, etc.) to the specific locations in
the /tftpboot directory.
The following instructions can be used to configure standard TFTP servers (BSD compatible)
that are under the control of xinetd.
Configuring a TFTP Server
To configure TFTP as root on the host, proceed as follows:
1. Create (or edit) the file /etc/xinetd.d/tftp. Use the following format:
#/etc/xinetd.d/tftp
service tftp{
