I think the reason it's not documented is that the actual implementation
depends on the specifics of the PXE server software you use. You need the
bzimage and the initrd supplied with unattended on your PXE server and then
configure the PXE server to make it available. Here's the relevant lines from
my pxelinux.cfg file on my PXE server, but yours will likely differ:
label utendl4.8
kernel utendl4.8/bzImage
append initrd=utendl4.8/initrd

There are a few ways to do this. I decided I didn't like to pass the variables
through PXE (and had trouble getting it to work, anyway) so I decided to
hard-code it into /etc/master - here's a copy of my documentation on how to
edit the initrd:
unpack existing initrd file using:
cat initrd | (cpio -i -d -m ; cpio -i -d -m)
change the files as required (this is where you could edit /etc/master to
specify the variables)
repack the image using (with current working directory as the root of the
unpacked image):
find . | cpio -o -H newc -O ../initrd
However this new image is missing /dev
To add it to the image you need devices.txt and mknod-cpio.pl from the
unattended CVS (you need to chmod mknod-cpio.pl to make it executable)
Edit devices.txt to remove all blank lines and all comment lines
./mknod-cpio.pl < devices.txt > devices.cpio
This will create a devices.cpio file, then:
cat devices.cpio >> initrd
to add the devices to the initrd image.
