From: Darrick J. Wong <djwong@xxxxxxxxxx> This new test requires a loop device to run testing. While it checks for some "obvious" parameters that might cause the test to fail such as not being root and no losetup executable, it doesn't actually check that the losetup -a call succeeds. This causes a test regression in my package building container (where there is only a minimal /dev with no loop devices available) so I can't build debian packages. Fix the test to skip out if we can't create a loop device. Signed-off-by: Darrick J.
