the .iso files on the nfs ?  I thought you put all the files IN the iso

personally, when I do PXE, I use a http style install off a local copy 
of the repository.   Its been a little while since i set it up, but 
IIRC, there's some mojo you put in the kickstart file on the tftproot to 
tell it what install type you want (nfs vs http vs whatever)
