[Fedora-livecd-list] eth0 and eth1 in kickstart

[Tim Wood]

After more testing and fiddling, it looks like I've solved all the 
problems.  The interfaces come up, everything functions and I can use 
iptables to configure the LiveCD as a gateway/router that another 
machine can use.  The process:

1) delete /etc/sysconfig/network-scripts/ifcfg-eth*.bak
2) grab some basic stuff (e.g. hwaddr) out of 
/etc/sysconfig/network-scripts/ifcfg-eth*
3) overwrite those config files as I want them
4) restart network (service network restart)

I'm not sure why the network init script is creating the .bak scripts 
(step 1) but they seem to be the cause of the "network unreachable" 
errors that  I get with some commands and not others.  I've tried 
various approaches to creating these files before the network init 
script runs and it overwrites them.  Of course if I dug into the code of 
that script and the things it drives I'd probably have a d'oh moment...
