I've got it working. I'm using the older stuff from Mythbuntu based on LTSP.
You use debbootstrap IIRC to create the base image, then set up the DHCP to
point clients to your server and run the tftp stuff on the server. When a
client boots it grabs the kernel and initrd from the tftp server then mounts
the base image over nbd and an overlay using NFS. The base image is
read-only and compressed via squashfs, all writes go to the NFS directory
created per client machine. I upgrade by chrooting into the client image,
run aptitude update; aptitude upgrade, then exit and run ltsp-update-image.
The clients need to be rebooted after this. There is also
ltsp-update-kernels in you need to update a kernel for the clients. Upgrades
haven't caused any significant problems.
There used to be documentation on the Ubuntu wiki for setting up the
PXE/LTSP stuff. I don't know if it's still there. It was based on Hardy
IIRC, but it works fine on the newer versions.
