The program gets the network configuration and uses a shell script for configuring the interface, and when receives the HUP signal, calls the shell script again for shutting down the tunnel, but it needs a few seconds for doing this.
What's the better way for doing this? at the moment, I do:
[Service]
WorkingDirectory=/var/lib/gogoc
Type=simple
EnvironmentFile=-/etc/sysconfig/gogoc
ExecStart=/usr/bin/gogoc -f /etc/gogoc/gogoc.conf $GOGOC_OPTS
ExecStop=/bin/kill -s SIGHUP $MAINPID
it sends the HUP, but then it kills the daemon immediately, there's no time for shutting down the tunnel properly.
Is correct to put a sleep? It looks awful
ExecStop=/bin/kill -s SIGHUP $MAINPID; sleep 5
What do you think?
