*: Use privileged decorator for service actions
Tests:

- DONE: Unit tests work
- DONE: Transmission
  - DONE: Enabling/disabling an app with a daemon works: transmission
  - DONE: Showing the status of whether the app is enabled with daemon
    is-enabled works.
  - DONE: A message is shown if app is enabled and service is not running
  - DONE: Service is stopped and re-started during backup
  - DONE: Adding user to share group during initial setup restarts the service
- Not tested: Enabling/disabling a service with alias works (no such apps)
- DONE: Restarting/try-restarting a service works
- DONE: Masking/unmasking works
  - DONE: rsyslog is masked after initial setup
  - DONE: systemd-journald is try-restarted during initial setup
- DONE: Avahi, email, security initial setup works
  - DONE: Fail2ban is unmasked and enabled
- DONE: Enabling/disabling fail2ban is security app works
- DONE: Enabling/disabling password authentication in SSH works
- ?? Let's encrypt
  - Services are try-restarted during certificate setup, obtain, renew
- Not tested: upgrade pagekite from version 1
