That may unnecessarily narrow down potential fixes for this
bug.  Of course it would be possible as well (and maybe
preferable) for "apt-get update" (and other commands?) to
create their temporary files elsewhere or, depending on com-
patibility and privilege considerations, use linkat(2) with
AT_EMPTY_PATH.
