Sure. I'd always wanted consistent names for the eth interfaces when I
set up the cluster but I couldn't get udev to co-operate. Maybe this
time! Let me try.

I don't have the particular file you mention. I do have the following files:

05-udev-early.rules 51-hotplug.rules 60-raw.rules
90-hal.rules bluetooth.rules
40-multipath.rules 60-net.rules 85-pcscd_ccid.rules
90-ib.rules
50-udev.rules 60-pcmcia.rules 90-dm.rules
95-pam-console.rules

Not sure how to proceed with udev, but maybe this is OT for this list.
