Thanks for answer, So, my binary "microupsd" is started by /etc/init.d/microups at the boot time to monitor power input, battery status etc. During system halt I need to send SIGUSR1 to this "microupsd" process at which it will send command to microups device, moreover I would like to give it some time (like 1-2 seconds) to accomplish the transmission. I don't need to send anything in case of reboot. Should I prepare some script that sends SIGUSR1 to "microupsd" process and then sleeps for 2 seconds and set it as WantedBy poweroff.target and halt.target ? How can I be sure that this script will be called before "microupsd" is actually killed during system shutdown ?
