[Ltib] How to get device nodes into zImage?

[Ned Konz]

I've been banging my head against this:

LTIB will make a zImage that contains most of the filesystem entries  
you need to run your system.

Unfortunately, it lacks any device nodes (there are only a few empty  
directories under /dev).

Later, a rootfs.ext2.gz may be produced that has all the proper device  
entries in it.

How can we get the device entries in the zImage? I've tried pointing  
the source for the INITRAMFS at the rootfs.tmp but it doesn't have the  
device entries yet.

What is the best way to get a fully - populated ramdisk image into the  
zImage -- with the device entries?

This is a lot easier than using a separate kernel image and rootfs  
image.
