Gaia/System/Updates: Difference between revisions

** More frequently than Gonk (kernel) updates.

** Based on input from carriers and OEMs, it is likely that updates will need to happen somewhere between the current Desktop (6 week) and Extended Support Release (42 week) intervals. The proposed requirement is to offer regular updates every 18 weeks. This frequency offers Mozilla and our partners the ability to update functionality on the device at a quicker pace than competitor OS stacks (iOS and Android), but at the same time not overwhelm our Carrier partners who may not be used to updating software so frequently.

* Backups:

** Requirements is to offer a back-up instance of Gecko to ensure we can failover when necessary (if we somehow shipped an updated Gecko version that resulted in a bug).

*** Will require restarting process (aprox 10 seconds), but not rebooting the device. Reboot _may_ be required as fail safe if /system is somehow left in read-write after the updater is finished.

*** Battery life: We can detect current battery level, but not drain rate (which varies with battery age). It will also be difficult to estimate the amount of power required to complete an install. Therefore we should build healthy margins into any "minimum required battery" thresholds.
