Comment 3 for bug 1471243

I do find it relatively silly that one of our providers has decided to set noatime on their base images (that's not been much help to anyone since linux 2.6.30 switched the default to relatime, so atime's not especially I/O-intensive any longer).

That aside, I agree that having your unit tests depend on options presented by the local machine's filesystem is not great from an isolation standpoint. Telling your developers what filesystem options they'll need to set or unset on their machines before they can run unit tests on patches they're writing/reviewing is sort of an awkward situation to be in as a project.
