if the parent of the directory of the entrypoint is not mounted/created
within the container image, then docker responds with an error about how
the target directory does not exist. We can avoid this error by mounting
the single file which docker recognizes as a "symlink"-style mount and
can ignore the fact that its parent directories may not exist
