Two things, I think:
The container should have a 'config' attribute:
containers.hound.config = import ...
And within the container config I think you must configure the systemd
service directly (there is no 'serviceConfig' option for 'services.hound'):
systemd.services.hound.serviceConfig = { ... }
I assume here that the 'services.hound' option generates a
'systemd.services.hound' config. I haven't checked though.
