Systemd startup in V5

Install, Configure and Update
1

Hi,

I’ve noticed since upgrading to V5 that the systemd startup of the CryoSPARC master is no longer working (it was fine for all v4.x versions). Has this method been deprecated? It was very useful to enable auto-restart of the master after a machine reboot.

We encountered a case where systemd integration did not work as expected and removed the related documentation from the guide. In case

  • you were satisfied with the systemd integration in CryoSPARC v4
  • and your current unit file’s ExecStart= line includes a parameter like
    -c /path/to/supervisord.conf

you can try whether omission of that
-c /path/to/supervisord.conf parameter results in a systemd configuration that works with CryoSPARC v5 at your site.

Thanks - I’ll give this a go.
