The Nextcloud administration overview page listed a bunch of deployment
configuration warnings that needed to be addressed:
* Set the default phone region
* Define a maintenance window starting at 0600 UTC
* Increase the PHP memory limit to 1GiB
* Increase the PHP OPCache interned strings buffer size
* Increase the allowed PHP OPcache memory limit
* Fix Apache rewrite rules for /.well-known paths
Fedora now includes a packaged version of Nextcloud. This will be
_much_ easier to maintain than the tarball-based distribution method.
There are some minor differences in how the Fedora package works,
compared to the upstream tarball. Notably, it puts the configuration
file in `/etc/` and makes it read-only, and it stores persistent data
separate from the application. These differences require modifications
to the Apache and PHP-FPM configuration, but the package also included
examples to make this easier. Since the `config.php` is read-only now,
it has to be managed by the configuration policy; it cannot be modified
by the Administration web UI.
