@joshdata squashed pull request #1398, removed some comments, and added these notes:
* The old init.d script for the management daemon is replaced with a systemd service.
* A systemd service configuration is added to configure permissions for munin on startup.
* nginx SSL settings are updated because nginx's options and defaults have changed, and we now enable http2.
* Automatic SSHFP record generation is updated to know that 22 is the default SSH daemon port, since it is no longer explicit in sshd_config.
* The dovecot-lucene package is dropped because the Mail-in-a-Box PPA where we built the package has not been updated for Ubuntu 18.04.
* The stock postgrey package is installed instead of the one from our PPA (which we no longer support), which loses the automatic whitelisting of DNSWL.org-whitelisted senders.
* Drop memcached and the status check for memcached, which we used to use with ownCloud long ago but are no longer installing.
* Other minor changes.

This reverts commit 82844ca651 ("make certbot auto-agree to TOS if NONINTERACTIVE=1 env var is set (#1399)") and instead *always* auto-agree. If we don't auto-agree, certbot asks the user interactively, but our "curl | bash" setup line does not permit interactive prompts, so certbot failed to register and all certificate things were broken until the command was re-run interactively.
Starting with 2.4, Z-Push no longer provides tarballs on their download server. The only options are getting the code from their git repository or using one of their distribution packages. Their Ubuntu 18.04 packaes don't seem to actually work in Ubuntu 18.04, so thinking ahead that's currently a bad choice. In 78d1c9be6e we switched from doing a git clone to using wget on their downloads server because of a problem with something related to stash.z-hub.io's SSL certificate. But wget also seems to work on their source code repository, so we can use that.
In 0088fb4553 I changed the management daemon's startup
script from a symlink to a Python script to a bash script that activated the new virtualenv
and then launched Python. As a result, the init.d script that starts the daemon would
write the pid of bash to the pidfile, and when trying to kill it, it would kill bash but
not the Python process.
Using exec to start Python fixes this problem by making the Python process have the pid
that the init.d script knows about.

The cryptography package has created all sorts of installation trouble over the last few years, probably because of mismatches between OS-installed packages and pip-installed packages. Using a virtualenv for all Python packages used by the management daemon should make sure everything is consistent.
See #1298, see #1264.
The PHP5 packages have a dependency on (apache2 or php5-cgi or php5-fpm), and since removing php5-fpm apache2 started getting installed during setup, which caused a conflict with nginx of course.
These packages don't seem to be needed by Roundcube or Nextcloud --- Roundcube includes the ones it needs.

* The Mozilla recommendations must have been updated in the last few years.
* The HSTS header must have >=6 months to get an A+ at ssllabs.com/ssltest.
