Series ubus: extend the service object with a restart method | expand

Commit Message

Florian Eckert Dec. 17, 2020, 9:35 a.m. UTC 
This commit adds the functions `procd_add_service_trigger` and
`procd_add_restart_service_trigger`. In order for the service to be
triggered by another service during a restart, only the function
procd_add_restart_service_trigger is needed.

Example:

service_trigger() {
	procd add_restart_service_trigger 'firewall' <command>
}

If the firewall is restarted, the specified <command> will be executed.
