I haven't really traced it (yet), but on some servers, I'm observing
`ansible-playbook ... --tags=start` completing very slowly, waiting
to stop services. I can't reproduce this on all Matrix servers I manage.
I suspect that either the systemd version is to blame or that some
specific service is not responding well to some `docker kill/rm` command.
`ExecStop` seems to work great in all cases and it's what we've been
using for a very long time, so I'm reverting to that.
* Upgrade Mjolnir from 1.1.20 to version 1.2.1
https://hub.docker.com/r/matrixdotorg/mjolnir/tags
using the "latest" tag seems inefficient as it doesn't actually redirect to the latest release
In any case, the latest release is now 1.2.1
docker pull matrixdotorg/mjolnir:v1.2.1
* Fixup

Until now, we were leaving services "enabled"
(symlinks in /etc/systemd/system/multi-user.target.wants/).
We clean these up now. Broken symlinks may still exist in older
installations that enabled/disabled services. We're not taking care
to fix these up. It's just a cosmetic defect anyway.
