Thank you for the feedback. I fear that there is a certain cultural gap. 
For example, I conside configure-make as essentially automatic. I'm 
optimisitic that a chapter about the used parts in front of the 
installation instructions could help.

I'm grateful for Igors instructions because they help to find the points 
that cause confusion and must be adressed.

It is always a good idea to give as much help in adavance as possible. 
There are still some problems to solve for docker. They are essentially 
a measure to assure that we do not run into a support avalanche:

- There should be a form of testing that checks whether the docker image 
does what it is supposed to do such that we can test it on any available 
configuration without effort. While tests on the software level are 
relatively simple, I have no idea how to properly test software 
installation: A typical example that such a test should catch are 
improper file permissions or components running under the wrong user.

- Are the used interface components guaranteed to be long-term stable? 
One of the major disadvantages of systemd against POSIX is that what 
works today not necessarily works tomorrow. The RemoteIPC setting is an 
example. This can or can not be better with docker.

- Do we understand the mechanics of docker good enough to find for any 
weird error message the underlying source of the problem? Please note 
that the two preceeding points are special cases of that variant. But 
things like typos or missing arguments may come on top.

- It should be clear that we do not require expierenced users of 
POSIX-based systems to do the extra detour of docker. This is mostly a 
documentation problem.

Best regards,
