tested on  a system without issue.

2) I then took that same ISO and dropped it in my pxelinux.cfg/default

label LiveCD
 kernel livecd/vmlinuz0
 append initrd=livecd/initrd0.img media=network
root=live:CDLABEL=F13-LiveCD-POC-20101201-122711 rootfstype=auto ro
liveimg rhgb rd_NO_LUKS rd_NO_MD rd_NO_DM ramdisk_size=164212
init=/bin/init  iso1=nfs://imagesrv/fedora-livecd.iso

if it works from a CD, it should work over PXELINUX. All help is
