Net (PXE) boot from a two interfaces computer

[Frédéric BOITEUX <fboiteux@calistel.com>]

	Hello,

  I'm trying to boot a Debian Live system from network (with PXE) on a
PC with 2 ethernet interfaces. It doesn't work because the bootable
ethernet interface (only one of the two) is recognized as 'eth1' by
udev, the other one as 'eth0', so the Debian Live system send
its DHCP request (to configure it, then mounting its filesystem by NFS)
on the wrong interface (it isn't connected).

  How can I do to use always the same Ethernet interface during the
whole boot process ?

	Fred.
