Cannot use docker transport when using docker tmpfs on /tmp

[RulerOf]

:ghost: Brief Description

When using a run_option to specify /tmp as a tmpfs, using the docker transport fails. This configuration is necessary to implement the recommended way to run systemd in a container.

Version

• kitchen-docker (2.11.0)

Environment

Mac OS with Docker Desktop 4.2.0

Scenario

The docker transport attempts to copy a shell script to /tmp inside of the container, but when it's declared as a tmpfs, this can silently fail.

Steps to Reproduce

This .kitchen.yml should do it:

---
driver:
  name: docker
  # Required by Systemd
  run_options:
    env: container=docker
    stop-signal: SIGRTMIN+3
    tmpfs:
      - /tmp
      - /run
  volume:
    - /sys/fs/cgroup:/sys/fs/cgroup:ro

transport:
  name: docker

provisioner:
  name: dummy

platforms:
  - name: oraclelinux-7

lifecycle:
  post_create:
    - remote: touch /tmp/test

suites:
  - name: default

Expected Result

The test should complete.

Actual Result

Heavily trimmed to show only relevant bits:

       Finished creating <default-oraclelinux-7> (0m1.28s).

:heavy_plus_sign: Additional context

I don't currently use this transport because it doesn't support kitchen login. That's a different issue that I'll probably open separately.
