CentOS - Jun 2008 - Booting Diskless Workstations

I made a post in the Fedora list that didn't yield much help regarding this.
I need to use a CentOS5.1 server to remotely boot a few Fedora 9
workstations. I have the option of using straight PXE, or even reflashing
gPXE to the LOM for the clients. What I am interested in knowing is the
best approach to this.

1. Should I just do iSCSI backed diskless setups? Probably doesn't scale
well.
2. I looked at ltsp, but I can't present a fc9 environment with a RH5.1
server?

The workstations would be fairly stateless, I intended on redirecting home dirs
to a persistent share that gets backed up.

Any ideas I can look into would be greatly appreciated!

Thanks,
jlc

What's wrong with NFS?  You can even have root on NFS these days
A quick google found:

My first thought:
Install a workstation as normal, then tar/untar them onto the NFS server.
With some correct seperation of files you should be able to share most
of the filesystem between machines (eg /usr could be readonly).  You
might even be able to make root readonly, but I've never tried that.
