I did verify there was a rogue DHCP server on this network which is handing out 
invalid IPs per the below logs. I guess Network Manager never bothers to ask for 
IP information if it receives an IP via DHCP during netinstall.

May  7 14:50:25 localhost dhclient[1497]: DHCPREQUEST on eth0 to 255.255.255.255 
port 67 (xid=0x7442ba23)
May  7 14:50:25 localhost dhclient[1497]: DHCPACK from 10.33.50.49 
(xid=0x7442ba23)
May  7 14:50:26 localhost dhclient[1497]: bound to 10.255.255.242 -- renewal in 
117 seconds.

Thanks for the quick response!
