crie um script sh:
nano unisonMonitor.sh
#! /bin/bash
su – root -c /usr/local/bin/unison default &
make it executable with
chmod +x unisonMonitor.sh
cd /etc/rc.d
nano rc.local
#! /bin/bash
touch /var/lock/subsys/local
sleep 6
/unisonMonitor.sh
chmod u+x
systemctl restart rc-local
systemctl status rc-local
reboot
login → ps aux | grep unison
Isso eventualmente funcionou para mim.
