+Subject: [PATCH] tests: Use script.scratch_path over script.temp_path
+
+script.temp_path is the system temporary directory. scripttest will
+check that there aren't any dangling files left in there, thus it's
+inappropriate to write long-lived packages there.
+
+These tests are currently passing as scripttest's temporary file
+detection logic is broken. However, a newer version of scripttest will
+fail.
