    trash test: Don't rely on being able to determine mount points
    
    If we can't find the mount point for target or tmp (as currently
    happens on Launchpad autobuilders, and perhaps relatedly, on a
    development system that uses btrfs), that's probably not great but is
    not really the point of this test.
