Perhaps on later Fedora systems.   On the F7 school servers I don't see
75-persistent-net-generator.rules.

Fedora 7 uses a cruder approach, adopted by the XS software, of
placing the device MAC address inside the network script (even if
there is only one device).    On first boot, the network-scripts are  
rewritten,
biasing the device assignment toward known reliable NICs as the WAN
port (eth0).
