%post DHCP?

[James Harrison]

When you run Post-installation scripts outside of a chroot'd environment 

For some reason (maybe its anaconda) networking settings are reset...

>From my experience Ive had to do the following:

%post --interpreter /bin/bash
#start network for on system
/sbin/service network start
/sbin/service portmap start

#mount a network drive on machine and cd into directory
mkdir /mnt/network 
mount ??.??.??.??:/kickstart /mnt/network 
cd /mnt/network/config-sys 
..
..

Forget Anaconda once you run the Post-install script in a chroot'd
environment. The above is using your newly installed OS and starting it in
single mode.
