systemd

[EwaldvanGeffen]

Hi, Just wanted to let you know how I did systemd. Just a suggestion, there might be even more native methods.

root@acerola:~# cat /etc/systemd/system/radioclkd2.service
[Unit]
Description=Radio Clock service
Before=chrony.service

[Service]
EnvironmentFile=/etc/default/radioclkd2
ExecStart=
ExecStart=/usr/local/bin/radioclkd2 $OPTS

[Install]
WantedBy=multi-user.target
Alias=radioclkd2
root@acerola:~# cat /etc/systemd/system/radioclkd2.service.d/set-gpio.conf 
[Service]
ExecStartPre=/usr/local/bin/setgpio.sh 13
root@acerola:~# cat /usr/local/bin/setgpio.sh 
#!/bin/sh
if [ ! -f /sys/class/gpio/gpio$1/value ]; then
  echo $1 > /sys/class/gpio/export 
fi
echo both > /sys/class/gpio/gpio$1/edge

I also adjusted some things in main.c; because I don't want to daemonize for systemd. Maybe there's a better way to integrate into systemd more natively.
