[opensuse] Disableing persistent NIC names

Hi, I have a case where I want to disable the persistence of NIC names. Actually I have a SuseStudio appliance that has to be used on different PC's. Every time I put the USB-stick in another PC there is another NIC name (ethx), and it's unconfigured. I would like to have always eth0, using the configuration of eth0. I found it has something to do with /etc/udev/rules.d/70.persistent-net.rules. Every NIC used has it's entry there. What is writing those rules ? Can it be disabled ? Other solutions ? Maybe erasing this file on shutdown, or maybe better on startup ? Thanks for any info. -- Met vriendelijke groeten, Koenraad Lelong
