Can the apt package

postinst

(or equivalent) have a

systemctl daemon-reload

added before you try restarting the client? Otherwise I have to run that and restart the client every time you update the service file

this is the postinst script any suggestions for improvement are welcome

#!/bin/sh
set -e
systemctl preset netclient

if [ "$1" = upgrade ]; then
    systemctl daemon-reload
    systemctl enable netclient
    systemctl restart netclient
fi

I don't think it's being hit, systemd complains each time that the daemon needs reloading. I'm no expert on systemd and haven't used

preset

. I would be tempted to change it about like this: systemctl daemon-reload systemctl preset netclient systemctl enable netclient systemctl restart netclient
