# We use ssh multiplexing, which creates sockets in /tmp.  Overlayfs,
# which docker is using, can't host sockets, so we use a scratch mount
# for /tmp.  This requires that we add --rm option to "docker run"
# invocations (e.g., mark "Remove volumes" checkbox in docker plugin) to
# cleanup host directories used for the scratch mounts.
