 If you only have one interface card, you don't necessarily have much
 use for this feature as the name almost always stays at eth0, you can
 easily disable it using forementioned methods.

 In a normal new installation there are no files in /etc/udev/rules.d
 and if you haven't edited any files you have in there, you should most
 likely backup and delete them all if they don't belong to any packages.
