In the `readiness` and `tests` functions, it is also possible to refer to global
configuration parameters:

The above functions also accept the same global configuration parameters, and

The Nix expression above is not self-contained. It is a function definition
that needs to be invoked with all the process managers and profiles that we
want to test for.
We can also configure other properties useful for testing:
* `systemPackages`: installs additional packages into the system profile of the
test virtual machine.
* `nixosConfig` defines a NixOS module with configuration properties that will
be added to the NixOS configuration of the test machine.
* `extraParams` propagates additional parameters to the processes model.

For process management solutions that rely on processes that daemonize on their
own (`sysvinit`, `bsdrc` and `disnix`), you need to consult the logs that are
managed by the services themselves (a daemon typically detaches itself from the
`stdout` and `stderr`. As a result, a process manager cannot do it).
