Loading CentOS 6 stops at very ending, Kickstart

I have this situation when i kickstarted new CentOS 6 machine with only installed thes group packages:

@ Base
@ KDE Desktop

When i booted into this new machine it almost loads completelly but NOT!:

Turns out that the operating system is NOT actually crushed.
I can press CTRL+ALT+F2 to log in from there.

So why this happen?

This happen because i i have created another afterscript which changes the default inittab to 5 whick means that i will boot staight into graphical interface:

sed -i "s/^id:3:initdefault:/id:5:initdefault:/" /etc/inittab

Not luckuly form me Dispaly Manager is not really installed and that is why i got the whole situation.

To solve this scenario i have to add "X Window System" before installing desktop:

@ Base
@ X Window System
@ KDE Desktop
