Please canonicalize output to: "mount: block device already mounted or mount point busy" so we can do away with _filter_scratch. _filter_scratch is not needed for overlay/036, but that is not the common case. And a nit: I would keep the word "or" in the left side. "already mounted or .*busy" is a nicer expression to read IMO.

util-linux v2.30 changed error message of a busy mount and caused overlay/036 to fail. e.g. - mount: <device> is already mounted or <mountpoint> busy + mount: <mountpoint>: <device> already mounted or mount point busy. Filter the mount output by a newly introduced _filter_busy_mount into a unified format.
