This brings a number of changes and improvements, and moves from MariaDB
to SQLite for storage, which requires manual migration for pre-existing
deployments using `prosody-migrator`.
Most importantly, this helps make WebRTC calls in XMPP more reliable
when either (or both) endpoints are behind NAT (as is the case with most
mobile devices), and avoids depending on a third-party service.
Default configuration has been applied in the virtual environment file;
this allows for setting up most host-dependent configuration easily.
This commit integrates WriteFreely as a systemd service, set up as a
single-user instance by default (as is probably appropriate for a
home-server setup); a default administrator is set up, and whoever
is managing the home-server is expected to update the username and
password after first login.
Though WriteFreely expects to have a hostname set up for the instance,
we do not listen on any specific hostname by default. It is expected,
rather, that the `nginx-proxy-http` service is used with a drop-in for
using the correct `writefreely` upstream.
Configuration for this will continue to evolve as required.
This is a basic implementation on top of the venerable `rss2email`
script, and is intended to be driven by a timer and the
`rss2email-subscribe` service, which manages the subscribed feeds.
This contains the culmination of work done privately for a few months,
and is intended to be a solid basis for other peoples' experimentations
with setting up single-node, home-server setups using Fedora CoreOS.
