Mike, I just pushed up a branch for Azure which supports reconfiguring network
on every boot (as well as generating network_config from their metadata service
which is a bit noisy given your needs).
https://code.launchpad.net/~chad.smith/cloud-init/+git/cloud-init/+merge/348704
A datasource subclass need only append EventType.BOOT to
DataSourceSmartOS.maintenance_events if their metadata service reports that
the user wants to maintain-network. This could be done idempotently (append
EventType.BOOT if not in self.maintenance_events) in your datasource's
_get_data() method based on whatever you metadata service tells it about
whether to maintain network per boot. I wouldn't expect your metadata service
to know anything about our internal EventType strings or constants, just to
interpret the proper EventType.<something> to add to supported/subscribed
maintenance_events. Cloud-init calls network_config only after _get_data is
processed, so if the datasource.maintenance_events is in the proper state after
_get_data, then network_config will either be generated or left untouched on a
normal reboot event.
