Decoupling the kernel and OS image should also mean we can do daily
builds of the OS snap for *all* devices. Previously, we had to line up
separate build pipelines for each device. But now we'll have a single OS
snap for all 64-bit x86, or 32-bit ARM, for example, and that can get
updated daily.

Testing on a small x86 box now. Thanks Michael!
