exec su -l gert -c 'export DISPLAY=:0; /data/location/server/process' method no longer works under Ubuntu 17.04. What is the new method for restarting a process after it dies...
Ubuntu 17.04 uses systemd for managing processes that previously were managed in Ubuntu by Upstart.
Specifically, the systemd
systemctl command is now used to start/stop/restart systemd services (e.g.,
sudo systemctl start dms3client.service). The
systemctl command does a bunch more too.
Here's a great explanation of how to use
systemctl right here on askbuntu.com: https://askubuntu.com/a/903360/32664.
