Would not be a bad idea to record enough information for the node (or
software running on the node) to talk back to MAAS. For example, a
unique shared key (readable only by root) together with the MAAS
location and API version.

This would allow, for example, the machine to update MAAS hardware
database without a reboot cycle.
