[K12OSN] k12ltsp as next-server

Hopefully, the following is correct and helpful. 

Have you set the correct option-path for the kernel in dhcpd.conf?

It will probably look like this for you, if *.66.150 is where the ltsp
kernels are

 option root-path ""; 
or if you are using nbd
option root-path "nbd:";

filename "/ltsp/i386/pxelinux.0"; only is for the pxe image. From there,
it needs to find its full kernel to finish booting

also, you will have to edit 
if you want your clients to connect to *.66.150 or anything other than
the default ip from install for the ldm session.
look for the server variable on line 46.
