Roll back OS to previous version

Haven’t really been to concerned about this capability (until now w/ the 2.0.2 editing bug).

Would it be possible to enable rolling back the OS to a previous version if an update temporarily caused some glitches?

It would be even better to be able to create your own SD card and flash any version of CorOS on it. This means you’d be able to roll back to any point desired, and you have redundancy on the road in case the SD card fails!
