   As all the files in that directory is run in alphabetical order and   
   "Original" comes after "70" the contents of the original file overwrote   
   the contents of your new file modified for your new hardware. This also   
   explains why your eth0 got renamed to something else when Original wanted   
   to use eth0 for another interface.

   Without any 70-persistent-net.rules a new file will be created at next   
   reboot only listing interfaces in your current hardware setup. The first   
   ethernet interface found will be named eth0.   
      
   However, if you before also had some other more or less custom files in /   
   etc/udev/rules.d not related to networking you might want to keep them. I   
   usually place custom files there which allow me to access different   
   hardware as digital cameras and GPS navigators as a normal user.
