[syslinux] PXELinux and serial number

[Scott Mewett]

Anyone have an idea if it would be a huge effort to get pxelinux to look
for config files based on serial number (available in DMI on modern
motherboards), much like we currently can use MAC address's.

Lots of our hardware comes with the serial number stuck on the chassis
but not the mac address. We'd like to move to pxelinux and still use the
serial number as the key for figuring which config is to be used.

For now I can have the system first boot a linux image that probes the
hardware, posts the mac addr and serial number to a database that has
the workload associated with the serial number. The database is then
able to correlate both can trigger the creation of a pxelinux config
file named after the mac addr associated with the serial number.

But it would be nice to be able to do that in one step, rather than two.

Thanks
Scott
