Options to be added to config.php, as a nix attribute set. Options containing secret data
should be set to an attribute set containing the attribute _secret - a string pointing to a
file containing the value the option should be set to. See the example to get a better
picture of this: in the resulting config.php file, the email.password key will be set to
the contents of the /var/keys/engelsystem/mail file.
See https://engelsystem.de/doc/admin/configuration/ for available options.
Note that the admin user login credentials cannot be set here - they always default to
admin:asdfasdf. Log in and change them immediately.
