Hi,
With git version, on nvOC restart (or nvOC start-service), I have:
Jul 22 15:37:30 m1-desktop systemd[1]: Started nvOC Service.
Jul 22 15:37:30 m1-desktop systemd[1]: nvoc.service: Service hold-off time over, scheduling restart.
Jul 22 15:37:30 m1-desktop systemd[1]: Stopped nvOC Service.
Jul 22 15:37:30 m1-desktop systemd[1]: nvoc.service: Start request repeated too quickly.
Jul 22 15:37:30 m1-desktop systemd[1]: Failed to start nvOC Service.
And I don't find any log about this.
