While doing a kickstart install, the network doesn't come up for %post, so all of our network based commands fail.  We are using the following 
net line

network --bootproto static --ip 192.168.6.231 --netmask 255.255.255.0 --gateway 192.168.6.1 --nameserver 192.168.6.253

The IPs have been changed to fake ones, but that's the same line.  The host doesn't have DNS entries, and isn't going to get them.  If it can't 
bring the net up automatically, i'd be perfectly willing to have the script do so at the beginning.  However, all attempts to bring the net up by 
hand using ifconfig, netstat, etc. have failed.  Please help, as it's becoming somewhat urgent and rather troubling.  If we ignore the errors and 
reboot the machine, we do end up with functioning networking.  Puzzled am I.

For your time I in advance give to you thanks
