It is at the moment used to id the interface that the MAC represents. (At a very early state in the process the MAC address is missing or only available from inside the partition.) The minimum PXE boot requirements need to be satisfied in general. The boot loader is part of the firmware and not loaded from the server. So that means the firmware needs to provide the MAC address. But the MAC address is not available at that time, so it's not available upfront. MaaS is using the same MAC address for the initial DHCP request as for the network boot. Hence an initially known MAC address is required that needs to be static and doesn't change (on subsequent boots for that instance). There might be an IBM internal ticket already open for this - please check. Furthermore the firmware needs to requests files like this: pxelinux.cfg/01-88-99-aa-bb-cc-dd pxelinux.cfg/default And BOOTIF support is required: See 'petitboot doesn't handle ipappend in pxelinux.cfg' https://bugs.launchpad.net/tasty-taco/+bug/1322307 for reference.
