I'm using Fedoras' "system-config-netboot" feature, which creates a 
network bootable system from a previously installed Fedora OS. It 
creates a "read only" base system, and r/w mounts parts that need to be 
written to. That way you can share the read only base between multiple 
clients, and they only take a few MB for their r/w data.
It also creates the pxelinux config, all you have to do is activate it 
in dhcpd.conf

I'm using a full blown Fedora image as read-only root (1.6GB), and the 
clients take up about 160MB (with 50MB v4l source and ~70MB vdr 
sources). The Client doesn't support PXE, so I used a Boot-CD created 
from www.rom-o-matic.net.
