remastering initrd

[Stuart Murray-Smith]

Greetings list :)

Calling all initrd ninjas! :) I need to customise/remaster an Ubuntu
9.04 initrd so that networking is available in a shell when I PXE-boot
a workstation.

Do I manually fold in networking (file-for-file, && where is the best
place to get documentation for this), or use a toolset (something like
initramfs-tools) to build a custom intrd?

Any insight/help highly appreciated as always :)

Stuart
