I've got a local package installing a systemd template unit file at /etc/systemd/system/koha-mq-scheduler@.service. Now all it takes it "systemctl start koha-mq-scheduler@INSTANCE.service" to start, but in hindsight it actually makes sense to use koha-mq-scheduler script to handle --enable, --disable, --start, --restart, and --stop. So I guess keeping the koha-* scripts makes sense but swapping out "daemon" with systemd template unit files instead. I suppose one thing to keep in mind is "adjust_paths_dev_install". I'm not familiar with that functionality.

I'm creating a service for a RabbitMQ-based task scheduler and my unit file is 17 declarative configuration lines. Creating a koha-mq-scheduler file looks like it'll be hundreds of lines of shell script code. My unit file is actually a "template" file, which means I have 1 file in /etc/systemd/system/koha-mq-scheduler@.service <mailto:/etc/systemd/system/koha-mq-scheduler@.service> and I can just invoke "systemctl start koha-mq-scheduler@INSTANCE.service <mailto:koha-mq-scheduler@INSTANCE.service> " to start the service. You can use the %i placeholder in the unit file and it will be replaced with INSTANCE, so you can set paths, environmental variables, et cetera very easily. It's so easy and convenient. I think all modern Linux OSes use systemd for their init system, so I think it would be pretty safe to use. I'm happy to work on this one, but I guess I'd like to see if other people have interest in this.
