Sometimes you’re forced to use old tools

Somebody’s playing in security. You need to use docker-machine because you can’t run native docker on localhost (last commit to docker-machine repo on github was made more than a year ago). And it doesn’t work from the box. So you’re tuning it up (like almost everything on Linux).

This time the problem was in names’ differences of default shared folder (host /home was mounted as /hosthome in guest vm, where actual docker engine runs), and rather loosy behaviour of -v, --volume option of docker run in comparison to more explicit --mount. See question answer on superuser.com.
