Recommended practice for device identification

I am vetting out RIOT-OS for an upcoming project where I will be creating *a lot* of devices, each of which need a UUID.

I was hoping someone might weigh in on the best way of "injecting" a unique ID into each and every device. Ideally this ID would be a true UUID (

For instance, is there a way to flash my binary (my app + RIOT-OS) to one place in ROM, and then the UUID to another location in ROM, and then hardcode the binary to "find" its UUID at the correct memory address?

Thanks, Zac
