RHEL5.4PXE, kickstart configuration details

This section describes the complete anaconda installation program. Strictly speaking, the full anaconda server requires dhcp, tftp, nfs, dns, vftpd, or http servers. Although dns is not involved in this section, but it can also complete the basic anaconda, which has been used in CentOS before. Now it is necessary to organize it again...
