DRBL (http://drbl.sourceforge.net/) will do a 'fat' client that
NFS-mounts the server so you have the option of running things
locally. There is also the k12linux project that bundles LTSP5.
I'm not sure if the Centos port was ever completed, but there is some
information here:

I too would suggest PXE booting the Live CD (I've done it with other
distros) - which brings me to the following questions regarding
CentOS.

RHEL write up [9] - also you might look at the Fedora docs below.



*** To anyone else who may know: ***

I found [0] and [7], but I'm curious if there is _any other method_.

Bits of Fedora discussion [1] [2] [3]
Fedora Docs [8] - basically copy files from a running system
Fedora dracut-network [4]
Amahi netboot [5]
Diskless (MythTV related, but applicable) [6]

I've used an unmodified ISO by loading it into memory via memdisk and
while that works ok it requires plenty of memory for the image. (But
it does not require any alteration done to the squashfs image.)

I've netbooted live Debian (and variants) off an NFS export (my
reading shows HTTP and FTP are an option too). I didn't succeed
pulling Fedora or CentOS images from NFS though.

Just curious.
(It would really rock if it was possible to load the squashfs over NFS
or HTTP rather than TFTP.)

If you haven't looked at drbl, it is mostly a collection of scripts
that set up the native tools in an assortment of ways. It can boot
into one of the clonezilla-live isos as an alternative to the stock
(server native) mode or into the installer images for several
distributions. I don't think the scripts accommodate generic live-cd
images, but it might not be too hard to add support. I've always
thought it would be nice to PXE-boot straight into an NX client
without needing NFS mounts, but haven't needed it badly enough to set
something up.
