Hi Johan,

Thanks for your comments, I'll try to implement the requested changes

Well the short commit message (i.e., the subject line) pretty much wraps
it all up in my opinion, hence no need for an extended commit message.
Is there anything in particular you would like to see or have explained
that requires an extended message? I would like to refrain from adding
an extended commit message just for the sake of having one.

I am afraid I don't quite follow. What exactly should I check? I am
pretty sure that the properties I used are described in the mentioned
yaml files.
