Kickstart Guide for RHEL

This post continued from PXE boot server setup but the propose of this is to create an automatic setup configure/script while install RHEL via PXE.
(refer to PXE boot server configure in previous post --> http://aflando.blogspot.com/2011/05/how-to-setup-pxe-boot-server-on-windows.html)

[Basic requirements]
1. Automatic install via NFS server(assume 192.168.8.184:/share/pxe already been shared)
2. Have a default value and let client click next to confirm or change it to own value.
3. Default value for keyboard, language and timezone.
4. Automatic add key(only AS5)
5. Start x windows on boot with GNOME
6. Interactive Network configuration
7. Firewall disabled (Not recommended)
8. Enable shadowed MD5 passwords
9. SELinux disabled (Not recommended)
10. Configure boot loader
11. Interactive disk layout
12. Automatic selecting package

[PXE boot server configuration]

Configure file C:\PXE\tftpboot\pxelinux.cfg\default
Example for AS4U8 :

label 32as4u8
menu label Install AS4U8 32bit
kernel /32as4u8/images/pxeboot/vmlinuz
append initrd=/32as4u8/images/pxeboot/initrd.img console=tty0 ks=nfs:192.168.8.184:/share/pxe/install/kickstart/32as4u8_ks.cfg ramdisk_size=268235456
