It can be, but /etc/udev/rules.d/70-persistent-net.rules tends to be
more important - it maps the MAC address to the device name. Then
you may also have the HWADDR=<MAC address> option in your
/etc/sysconfig/network-scripts/ifcfg=eth? file. That will provent
the interface from coming up if the MAC address of the NIC does not

You can edit the 70-persistent-net.rules file, or you can delete it
if you want to renumber the NICs. It will be re-created for you the
next time you boot. Change the HWADDR= value requires you do edit
the ifcfg-eth? file. (Hand edit or GUI.)
