Why not simplify this a little.
* Computer always boots via PXELINUX
* Boots into COMBOOT code
* Code always sends MAC addr,RAM,HDD size, Video Card to "Server"
* Server sends command to execute
* Computer executes command
The server can easily do the checking whether it is the first time or
not. It can return any PXELINUX image name, so it could be anything from
"reboot","chain.c32 hd0 1","ghost". Theoretically you should be able to
do this. some potential issues (I dont know if they are that difficult).
(1) Comboot code doing raw sockets or may be there is a way to piggy
back this info on top of the DHCP protocol.
(2) Is security an issue, i.e. what if there is a rogue laptop sitting
on the network posing as the server.
(3) You have to take the time to write such a code. I cant think of a
solution already out there which does it for you.
