I don't know how I did my check last time, but I was wrong. The changes
merged above fixed issues about tools being confused with the unexpected
st_dev values on files but they did not fix the fact that overlayfs
might return EXDEV when renaming a directory that is part of the lower
layer.

So I'm opening the bug again.
