Although the package itself builds fine, the module fails because it tries to log into a non-existant file in `/var/log` which breaks the service. Patching to default config to log to stdout by default fixes the issue. Additionally this is the better solution as NixOS heavily relies on systemd (and thus journald) for logging. Also, the runtime relies on `/etc/localtime` to start, as it's not required by the module system we set UTC as sensitive default when using the module. To ensure that the service's basic functionality is available, a simple NixOS test has been added.
