Instead of manuall relying in
$$
being unique, with this patch we instead usemktemp
which creates a unique, temporary file which we can use later. This also removes the possibility that we accidentially overwrite other existing files in the final location, e.g., from previous, failed runs.Via the default behavior of
mktemp
with this patch we also switch from forced generation of temporary files in/tmp
to possibly$TMPDIR
if set.
