RHEL 5.2, kickstart - and 2 questions

Hi,

I have RHEL 5.2. I prepared customized iso with my kickstart file.
On iso, in Server catalog I have some RPM packages.
In %post section I want to give command to anaconda - to install
this packages. In ks.cfg I have:


%post --interpreter=/bin/bash

/sbin/chkconfig --level 345 httpd on
cd /mnt/source/Server
rpm -Uvh some_packages.rpm

The problem is that anaconda while installation dont want to install
some_packages.rpm :(
Maybe command "cd /mnt/source/Server" is wrong? How in other way
can I access catalog Server on my DVD?

Last question. How force anaconda (in kickstart file) to enable
network configuration during installation? In my ks.cfg
I have no command "network" - however during installation there is
no question about network configuration.....

very thanks, regards.
