This refers to my last post bug or feature in oracle -rdbms-server-12cR1-preinstall
There is no problem in oracle-rdbms-server-12cR1-preinstall, but rather a little confusion in the docker image breed85/oracle-12:preinstall.

bug or feature in oracle-rdbms-server-12cR1-preinstall?
The latest version of oracle-rdbms-server-12cR1-preinstall introduces an interesting behaviour: it blocks su - oracle with the vacuous message su: could not open session. But we really need to be able to do that, when we want to install Oracle12c.

"Docker is managed via upstart, try using service docker restart" - baffling advice ?
Presumably every docker user has already followed this advice and experienced a baffling message "unkown job docker". There are quite a lot of questions and some bug reports in the net, but seemingly no satisfying answers. The question seems to me: "What is upstart?" Here is my own workaround.

Vagrant vs. VirtualBox ? - A false contradiction
"Why should I use Vagrant instead of just VirtualBox?" - There are quite a lot of questions and answers of that type in the net. The questioners seem to belong to the group of operations engineers, e.g. application supporters, database administrators, etc. The answerers seem to belong to the group of developers. Hence my first clue on this queer debate is, that it may be a question of conflicting priorities in the field of the Devops movement.
