Description of problem:
I'm doing a kickstart install over network, in interactive mode.
The resulting machine is set up to use DHCP.
The install goes well, but the post-install part fails.

When outside the chroot, the resolv.conf is ok, it does contains
'search' and 'nameserver' entries. But when inside the chroot, thus
where my post-install script is running, the resolv.conf only contains
the 'search' entry, and thus all DNS request are failing and therefore
the post-install script does not run properly.

if workarounded that by adding this at the very beginning of the %post
section :
echo "nameserver ip_of_my_name_server" >> /etc/resolv.conf

Version-Release number of selected component (if applicable):
anaconda-10.0-5

How reproducible:
Always

Steps to Reproduce:
1. do a kickstart install over the network, with the resulting machine
set to use DHCP
2. run a chroot'ed post install script that is supposed to do DNS
request (e.g. yum -y update)
3. 
    

Actual Results:  chroot'ed post-install script is not able to perform
DNS request

Expected Results:  chroot'ed post-install script is able to perform
DNS request
