We should probably provide an example config file on the Wiki that incorporates all this.. or maybe a diff. We also need to evaluate what the merit of all of this is.

There are Debian-derived distros that avoid systemd. -- hendrik

The config files are then in /opt/solr/server/solr/dovecot/conf and datafiles in /opt/solr/server/solr/dovecot/dataOn my system (Debian) these directories are wildly different (e.g. data is under /var), but other than that, this information is OK. Used this as a side-reference for Debian installation: https://tecadmin.net/install-apache-solr-on-debian/ Accessed http://solr-host.tld:8983/solr/ to check whether all is OK.
