Comment 11 for bug 1712817

Based on https://irclogs.ubuntu.com/2018/04/13/%23ubuntu-devel.html#t11:56, this sounds valid for either init-system-helpers or debhelper.

13:47 <xnox> rbasak, the description sounds valid. i believe i have hit something similar before, thus yeah a fix to debhelper for this class of issues would be most welcomed.

13:47 <rbasak> xnox: thanks. debhelper, or invoke-rc.d?

13:48 <xnox> rbasak, my understanding was that maintainer scripts that are generated, do attempt to check if a thing was "enabled and active" before the upgrade; and post upgrade. But maybe they only do so for systemd native units, and not for init.d->systemd units.
