Linux, for now.
I can understand that is different on each distributions, but on a PXE 
Boot its the same for all client, no?

I'm trying to understand why UUID/GUID is not supported at PXE Boot by 
the DHCP.

In fact, I'm afraid about a end user which can change the MAC Address 
and trying to request another IP. Because I use fixed address for each 
client. So I want to use fixed address by the UUID which can not be changed.

I'm not sure if I'm clear... :/
