[Qemu-block] [PATCH 1/7] qemu-iotests: check: don't place files with pre


From: Sascha Silbe
Subject: [Qemu-block] [PATCH 1/7] qemu-iotests: check: don't place files with predictable names in /tmp
Date: Tue, 5 Apr 2016 11:21:43 +0200

Placing files with predictable or even hard-coded names in /tmp is a
security risk and can prevent or disturb operation on a multi-user
machine. Place them inside the "scratch" directory instead, as we
already do for most other test-related files.
