If you are using the network service and DHCP, ifcfg-eth0 should look something like this:
DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes HWADDR=<MAC address> DHCP_HOSTNAME=<something> TYPE=Ethernet IPV6INIT=no NM_CONTROLLED=no USERCTL=no
You don't need all of this - you could get by with:
DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes NM_CONTROLLED=no
I really suggest using the MAC field, it prevents learning about Plauger's Law (law of least astonishment) the hard way... Of course the O.P. was using the MAC field (I suspect) and didn't know it.
You should also be able to create it using system-config-network.
Indeed. And I believe that should be part of the default install again.

With /etc/udev/rules.d/70-persistent-net.rules, you are probably not going to run into it if you do not use HWADDR in ifcfg-eth? On the other hand, I do tend to use something like the first example I gave - you don't need to, but it can prevent surprises.
