Bug#921237: bcfg2-server does not properly shutdown



Package: bcfg2-server
Version: 1.4.0~pre2+git141-g6d40dace6358-1
Severity: normal
Tags: patch upstream

Dear Maintainer,

bcfg2-server cannot be properly shutdown by systemd. Instead it runs
into a timeout and has to be killed by systemd. This is inconvent and
severly slows down the shutdown of the entire system.

This is an upstream bug that has been fixed in git by now:
https://github.com/Bcfg2/bcfg2/commit/020b8cfd398de6730f5767abbc1f587c899138f5

Is it possible to include this as a patch in the Debian package? I
assume it affects not only stretch but buster and sid as well.
