feat(preinit): support alternative roots In A/B schemas, it is possible to have multiple rootfs. Thus, it is necessary to let the B kernel preinitialize either the A rootfs or the B rootfs failing to mount the A rootfs. Ideally, we should also try to switch to the B rootfs if we cannot start up the init on the A rootfs, but that's a FUTUREWORK.
