Slackware udev stop rename eth 70-persistent-net.rules

I have like 50 hard drives copied with Slackware 12.2 as multimedia players,
And the udev renaming the eth0 and eth1 to eth2 eth* was giving me some troubles.
Reason for renaming: different /original/ MAc address specified in /etc/udev/rules.d/70-persistent-net.rules
Solution :
IMPORTANT: do that before to copy the hd 🙂
rm /etc/udev/rules.d/70-persistent-net.rules
touch /etc/udev/rules.d/75-persistent-net-generator.rules
thats it all,
explanation:
the empty /etc/udev/rules.d/75-persistent-net-generator.rules will prevent creation of 70-persistent-net.rules and the eth devices will be not renamed.
