I discussed on #openstack-infra. Rackspace recently changed kernel boot options on base images recently. So maybe the noatime option was added during this change.

There are two options to fix this issue:

* Convert the Glance unit test to a Glance functional test: for a functional test, we have the full control on the system (root access), you can remount the root fs (/) with the "right" mount option (atime, relatime, etc.)

* Mock the filesystem, at least the atime timestamp, in the unit test

IHMO the latter is simpler, but I didn't have time yet to check if it's feasible.
