Description of problem:

During an automated text-mode anaconda installation (configured with a kickstart file), anaconda fails with the following error message :

" | Network Error |
There was an error configuring your network interface. "

At this point, the target computer have been configured with DHCP and can be pinged. 
Hitting "Retry" will destroy the networking configuration, rendering the machine unpingable.


However, the shell on pty/2 is not available, and sshd is not started (having given sshd in pxelinux append= parameter, and set "sshpw" entries in kickstart).


Version-Release number of selected component (if applicable):
Default anaconda with F14


How reproducible:
Transient error / happens about half the time on our setup (DHCP via dhcrelay).
PXE boot, which uses same DHCP server, works 100% of the time.


Steps to Reproduce:
1. (may or may not be relevant) Have subnets 10.0.0.0/24 and 10.0.1.0/24, dhcpd on 10.0.1.1, routing box sitting on both 10.0.0.1 and 10.0.1.254 with dhcrelay
2. use cobbler to pxe boot into anaconda
3. watch failure, or retry until it happens
  
Actual results:

Network fails about half the time, otherwise installs just fine

Expected results:

Installation proceeds everytime
