predefine interfaces by MAC with udev?

[christopher.fanning at gmail.com (Chris Fanning)]

Hi,

We're trying to boot diskless servers that have two network interfaces.

We boot from one interface (dhcpd/MAC), but when initramfs kicks in,
udev (isn't it?) sets the interface names and then (often) the boots
process fails becuase it's looking for the filesystem on the wrong
interface.

We can't use the MAC as an option for 'ifconfig' or 'ip add add', so
we need to change something with udev, right?

KERNEL=="eth*", SYSFS{address}=="00:12:34:fe:dc:ba", NAME="eth0"
KERNEL=="eth*", SYSFS{address}=="00:56:78:98:76:54", NAME="eth1"

I've looked around the scripts but nothing as jumped out at me.

What would you do?

Thanks.
Chris.
