There was a problem hiding this comment.
This function doesn't have any unit tests so I think, given the subtle nature of this bug, we need one.

With kata-containers#1485, we moved the default medium empty-dir creation to the sandbox rootfs. This worked for devicemapper, but in case of overlay the "local" directory was being created outside the sandbox rootfs. As a result we were seeing the behaviour seen in kata-containers#1818.

Looks this PR make the behavior of overlay identical to DeviceMapper, which is good to me. While having chatted with @bergwolf, he has some other suggestions. |
