snapshotterboolean.Sometimes a flaky test is trying to tell you something 😄 The intermittent failures of
TestImageUsagewere actually always reporting the same "offset"; turns out that offset was the exact size of the unpacked root fs of the busybox amd64 build. What was happening is since busybox is used throughout other tests, a snapshot was created that was sometimes not garbage collected by the timeTestImageUsageran, and therefore since the label was associated with the amd64 manifest, it would be added to the size calculation and cause this test to fail.// cc: @fuweid since I know you had tried to fix this at one point; I also added a deferred deletion of the image reference pinned to the sha256 in the test as when you run it locally multiple times you still get wrong results unless both images are removed. A possibly more "stable" result would be to use a totally different image name that isn't used by any other tests.
