Tests done:
1. Install the email app with version 4, then check out the files:
```
ls -la /var/lib/rspamd/dkim/ ; cat /etc/rspamd/local.d/dkim_signing.conf
total 4
dr-x------ 1 _rspamd _rspamd 50 Jan 1 19:14 .
drwxr-x--- 1 _rspamd _rspamd 16936 Jan 1 20:21 ..
-r-------- 1 root root 1704 Jan 1 19:14 freedombox.local.dkim.key
cat: /etc/rspamd/local.d/dkim_signing.conf: No such file or directory
```
2. Apply the patches and update the app:
```
ls -la /var/lib/rspamd/dkim/ ; cat /etc/rspamd/local.d/dkim_signing.conf
total 4
dr-x------ 1 _rspamd _rspamd 50 Jan 1 19:14 .
drwxr-x--- 1 _rspamd _rspamd 16936 Jan 1 20:22 ..
-r-------- 1 _rspamd _rspamd 1704 Jan 1 19:14 freedombox.local.dkim.key
allow_username_mismatch = true;
sign_authenticated = true;
use_domain = "header";
domain {
freedombox.local {
path = "/var/lib/rspamd/dkim/freedombox.local.dkim.key";
selector = "dkim";
}
}
```
3. Configure example.com as a domain under Name Services, then also change the primary domain in the email app and confirm it completes without errors.
Also see:
```
ls -la /var/lib/rspamd/dkim/ ; cat /etc/rspamd/local.d/dkim_signing.conf
total 8
dr-x------ 1 _rspamd _rspamd 90 Jan 1 21:15 .
drwxr-x--- 1 _rspamd _rspamd 16936 Jan 1 21:17 ..
-r-------- 1 _rspamd _rspamd 1704 Jan 1 21:15 example.com.dkim.key
-r-------- 1 _rspamd _rspamd 1704 Jan 1 19:14 freedombox.local.dkim.key
allow_username_mismatch = true;
sign_authenticated = true;
use_domain = "header";
domain {
example.com {
path = "/var/lib/rspamd/dkim/example.com.dkim.key";
selector = "dkim";
}
}
```
4. Uninstall the app and perform a fresh install, confirm it completes succesfully.
The configurations in /etc/rspamd/local.d/dkim_signing.conf have been
verified to work on a throw-away VPS setup.

- This will leave /etc/{plinth,freedombox} empty by default making service more
robust to run across various environments and situations. See systemd's
explanation for more details.
- Use Debian maintainer scripts remove all the existing files in
/etc/plinth/modules-enabled.
- Read from /usr/share/freedombox/modules-enabled then from
/etc/plinth/modules-enabled and finally from /etc/freedombox/modules-enabled.
Later read ones override previously read files. Any file pointing to /dev/null
will mean the module must be ignored.
Tests:
- Clean up /etc/plinth, /etc/freedombox and
/usr/share/freedombox/modules-enabled. Run service and notice that files are
getting loaded from development folder using a debug message.
- Run setup.py and notice that files get installed in
/usr/share/freedombox/modules-enabled/ and in the next run they get loaded from
there.
- Create a override file in /etc/plinth/modules-enabled/transmission and notice
that overriden file gets priority over the one in
/usr/share/freedombox/modules-enabled.
- Link the file /etc/plinth/modules-enabled/transmission to /dev/null and notice
that is not loaded.
- Create another file in /etc/freedombox/modules-enabled/transmission and notice
that it overrides the previous two files.
- All affected modules are loaded.
- Build a new Debian package and ensure that upgrading 23.8 to new version
removes are all configuration files.
- Build developer documentation and test that Tutorial -> Full Code and Tutorial
-> Skeleton sections have been updated with references to
-.../modules-enabled/... paths.
- Install quassel and notice that certificates were copied to /var/lib/quassel
directory. Change domain to another domain and notice that certificates were
copied again to that directory.
