If you don't want to reinvent the wheel, I would suggest:

  http://www.perceus.org/

This site covers the Warewulf and new Perceus cluster toolset.
There is also

  http://www.onesis.org/index.php

If you do want to re-invent the wheel (to learn about
cluster provisioning etc.) then check out the NFS Root
HowTo on the Onesis page.

> Hi,
>
> I'm trying to set up my first cluster with diskless nodes. To achieve
> that, I'm using PXElinux on a server, running Fedora Core 6, and a
> NFS-mounted root partition on the node. Everything works perfectly
> (getting the IP address, loading the kernel and mounting the
> filesytem) until the node has to run some binaries located into /sbin
> during the boot process. Apparently it's unable to execute them
> because they have been compiled with dynamically linked libraries and
> not statically. The /sbin directory of the node is a simple copy of
> the one of the server. I tried to avoid the problem using the busybox
> tools, and it worked a bit better but then it couldn't execute bash
> scripts such as rc.sysinit.
> As anybody ever encountered such problems and what should I do to
> solve it? recompile the kernel of the node or of the server? change
> the distribution? Are there any other simpler method to proceed than
> using PXE?
>
> Thanks a lot for helping,
