Comment 14 for bug 1523476

FYI:

There's another patch that is intended to fix the same problem from Ivan Suzdal -

  https://review.openstack.org/#/c/255272/4

However, I don't like it patch. Despite the fact it fixes the issue on systemd side, it fixes it ugly - by wrapping services in bash process, and redirecting stderr/stdout into hardcoded file. It's done because apparently systemd doesn't support redirecting of standard output streams to files. The approach they recommend is to configure logging on application side.

So I think that should be fixed on application side, besides that would be convenient to setup output log filename through some settings.yaml (do not hardcode it somewhere).
