If so - although I can see this would work, I'm no better off than editing the /lib/udev/write_net_rules am I? > Either you have really old udev version or your distribution installs standard rules under /etc instead of under /lib.

Current udev reads /etc/udev/rules.d, /lib/udev/rules.d and one more directory under /dev for rules generated when root was still read-only.
