This flag is necessary for Ansible to ask for the sudo password when using the non-root option as documented in the `hosts` file. Otherwise, Ansible errors out with `missing sudo password`.
This is mostly here to guard against problems happening
due to server migration and doing `chown -R matrix:matrix /matrix`.
Normally, the file is owned by `1000:1000`, as expected.
If ownership changes, Dimension could still start, but it will fail the
first time it tries to write to the database. Explicitly chowning
before startup guards against this.
Related to #485 and #486 (Github Pull Requests).

Dimension runs as the `node` user in the container (`1000:1000`).
It doesn't seem like we have a way around it. Thus, its configuration
must also be readable by that user (or group, in this case).
We don't really need to fail in such a spectactular way,
but it's probably good to do. It will only happen for people
who are defining their own user/group id, which is rare.
It seems like a good idea to tell them that this doesn't work
as they expect anymore and to ask them to remove these variables,
which otherwise give them a fake sense of hope.
Related to #486 (Github Pull Request).
If one runs the playbook with `--tags=setup-all`, it would have been
fine.
But running with a specific tag (e.g. `--tags=setup-riot-web`) would
have made that initialization be skipped, and the `matrix-riot-web` role
would fail, due to missing variables.
Ansible will migrate the ownership of the base path and config path, but
manual intervention will be required in order to migrate the ownership
of files in those directories (i.e. dimension.db).
Stop the services:
(local)$ ansible-playbook -i inventory/hosts setup.yml --tags=stop
Fix the permissions on the server:
(server)# chown -Rv "{{ matrix_user_username }}:{{ matrix_user_username }}" "{{ matrix_dimension_base_path }}"
which would typically look like:
(server)# chown -Rv matrix:matrix /matrix/dimension/
Reconfigure Dimension and start the services:
(local)$ ansible-playbook -i inventory/hosts setup.yml --tags=setup-dimension,start
* add permalinkPrefix to riot-web config
* add feature to change default theme of riot-web via its config file
* remove matrix_riot_web_change_default_theme and provide sane default
