Diskless? Like in no floppy / thumb drives or diskless like in network booting?

If you want a thin client setup (diskless machines only run X and log into the server), the easy way is to install the k12ltsp version that has a centos base (version 5-EL from the download link here http://k12ltsp.org/mediawiki/index.php/Main_Page). If you want to NFS mount disks from the server and run everything on the clients or boot a single image on a cluster, look at http://drbl.sourceforge.net/. You can do either of these with the tools included in Centos yourself, but since it is fairly complicated it is probably worth trying one or both of these first.

Have a look at The Linux Terminal Server Project. http://www.ltsp.org/ That's is about the easiest configuration out.
You can use rsync to make the Client OS Layout and manually edit all files as needed, pxe dhcp nfs and tftp. It's a nightmare to do.
An alternative method would be obtain the "system-config-netboot" package from Fedora Core 6 or 7 that's if you can get it to work correctly. Red Hat omitted it in v5.0 and also I think in 5.1. Bugzilla on red hat says they are going to release it in a later release.
IMHO I believe it is getting replaced by cobbler. Any one on the list know for sure?

I have a small guide to setting up an NFS server and then dishing out diskless clients across PXE booting. It's out of date as I've not had time to update it to pertain to CentOS 5.1 explicitly, but it should be relevant and almost the same.

Well, what are you after? A Network Install or Diskless Install? If you want a Diskless Environment then you need to reconfigure your server. Do you have /etc/exports configured? You need to give a little bit more info on what you have done so far.

Ignore my previous post to you. I see your problem and it did not register in my brain untill today. This will not work in CentOS 5.0 or 5.1. Currently there is no workaround that is *KNOWN* to just work. That is using the "system-config-netboot package".
You can take and do everything in the following link for the Latest CentOS version 4 Update 6 and it will just plain out work. http://wiki.centos.org/HowTos/DisklessClients . The only other option you have if you have to run CentOS 5 and > is to use Cobbler. Cobbler is available in the CentOS Testing repository but there is very slim support for it. More information is available from here: http://cobbler.et.redhat.com/ .

Why is that the only option ? it takes 6 seconds to write the /tftpboot/ specs. Given a set of decent docs, anyone can just do that.

I am also not sure what you mean by there is very slim support for it. Its in very wide scale use in many thousands of places, there is a very active community behind it and there are a lot of CentOS users using it as well. How did you work out there was very slim support for it ?
