As mentioned in this post, a PXE request contains a GUID / UUID value.
Is there a way to refer this GUID / UUID in dhcp script?

I'd like to implement like below:
1. execute PXE Boot
2. send DHCP request to dhsmasq
3. hook dhcp-script which does:
  - refer UUID of the client
  - take the the client information from CMDB
  - create pxelinux.cfg/<UUID> with the taken information(e.g. RAID type,
kernel version)
4. send DHCP response to the host
5. booting goes on ...

Of course, it is possible to use the MAC address of NIC in place of UUID,
but it can be changed by repair and replacement and the priority of UUID is
higher than the MAC address of NIC for pxelinux.
So it's great if GUID / UUID can be referred in dhcp script.
