psi-alerts/CONFIGURE.md

CONFIGURE

Included in this project are a number of systemd units: * psi-monitor.service * uses psi-monitor executable (in /usr/bin/) * psi-alerts@.service (system template service) * uses psi-alerts.sh script

The psi-alerts.sh is essentially a daemon (a systemd simple service), and for now the systemd template needs to be instantiated with the username that will execute psi-alerts.sh. Also, a systemd unit override should be created, like so:

sudo systemctl edit psi-alerts@<user>.service

This will open an editor, and in later versions of systemd the comment code will be included, clearly showing where the override should be entered:
