In the cloud, all boots are non-interactive with keyboard and console access either typically not available or prohibited. Also clouds always do firstboot via fallback. This currently results in an unacceptable 5s boot delay whilst fallback offers interactive reset options that cannot be actioned. In Ubuntu, we'd like to make fallback noninteractive by default without any boot delays, due to bootspeed impact on firstboot of the preinstalled images.

Looks sensible to me. |

I'm on the GCE team that's dealt with this, can confirm it saves ~5 seconds on the first boot of a newer GCE instance |
