** Description changed: [Impact] Images built with pre-seeded snaps contain insufficient assertion data causing boot to fail. The snaps for seeding are downloaded with a custom snap tool for an earlier cohort API (now deprecated). The assertions that it pulls are incomplete. We could update that list and move to the new API but at this time the snap-tool provides no value compared to use of the snap CLI (cohort support has moved to the cli as well). The development overhead of maintaining snap-tool in livecd-rootfs are not warranted. This patch removes the bespoke snap-tool and relies on the snap CLI instead. [Test Case] - * Produce images that include preseeded snaps (in + * Produce images that include preseeded snaps (in /var/lib/snapd/seed/*) - * Boot the resulting image and ensure that the snapd.seeded unit is + * Boot the resulting image and ensure that the snapd.seeded unit is successful and the snaps (from the correct channels) show up in 'snap list' [Regression Potential] - * The interface for these two tools is consistent and the output should + * The interface for these two tools is consistent and the output should be the same. There's always a chance that snap-tool had quirks which a move to the snap CLI uncovers, where the result would be different snaps seeded from before the change. An example would be channel differences before and after this change. I haven't seen issues in my testing and I do think it's unlikely, mostly I'm suspicious of SRUs that don't list any regression potentials. + + [Other Info] + + * The attached MP for Xenial is simpler as it never had snap-tool.
