As this has now landed, the seed merge can go ahead -- this will unbreak
the flash-kernel operation on the dailies, and should unbreak upgrades
from plucky->questing (devel).

Title:
Support tryboot's A/B booting on Raspberry Pi
Status in flash-kernel package in Ubuntu:
Fix Released
Status in ubuntu-meta package in Ubuntu:
Triaged
Bug description:
The Raspberry Pi's tryboot mechanism [1] permits an A/B booting
structure that permits fallback in the event of bad boot assets (or a
bad boot configuration). We already substantially patch flash-kernel
for the Raspberry Pi (to permit moving an image between boards); we
should adjust the existing "pi" method (or add a new "pi-something"
method) to write new boot assets to a temporary location from which
they can be tested with the "tryboot" mechanism.
