Eth0 is not active at Linux Fedora Startup

Sometimes even though you have configure such that "Activate device when computer starts" for eth0 in Linux Fedora, it appears to do nothing - eth0 is not active at startup.

This maybe a bug with Fedora. One way to overcome this issue is to execute the following command:

chkconfig network on

This will enable the network service to be started on every time the machine boot.
