Clean up to avoid unnecessary notices and service restarts

Here are some tweaks I've been using for the past few months in my own fork which would avoid the notices being generated while using foreman, keeping the host being marked as active as it's not receiving the exit 0. Also without these changes, the broker service would be restarted every 30 minutes.

selinux_ignore_defaults is required to avoid the back and forth switching of label type.
Arrows should be aligned.
