predefine interfaces by MAC with udev?

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

Hola,

Well, I think I'm onto something..
It seems that my /etc/udev/rules.d/z25_persistent-net.rules never gets
written to.
And then I discovered that /lib/udev/write_net_rules is not copied to
the ramfs image.

So I edited
/etc/initramfs-tools/hooks/udev
and added it (plus other things just incase)

cp /lib/udev/net.agent $DESTDIR/lib/udev/
cp /lib/udev/udev_run_hotplugd $DESTDIR/lib/udev/
cp /lib/udev/write_net_rules $DESTDIR/lib/udev/
cp /lib/udev/udev_run_devd $DESTDIR/lib/udev/

And it works!
/etc/udev/rules.d/z25_persistent-net.rules is populated and respected.

I'll get back if this fails under more testing. :)
Chris.
