Update strategy for factory devices with RESIN_SUPERVISOR INSTANT_UPDATE_TRIGGER

Product support

Hi,
quick question: we have set RESIN_SUPERVISOR_INSTANT_UPDATE_TRIGGER to false and defined a RESIN_SUPERVISOR_POLL_INTERVAL
What is happening when I turn on devices that have preloaded images on their SD card and are registered using balena device register process?
Will they update immediately upon first boot or will they start the preloaded image and at a random time start updating?
Documentation is not fully clear on that.

Thanks!
Fritz

Hi Fritz, the preloaded images will first start and then at a random time the update will trigger. The RESIN_SUPERVISOR_INSTANT_UPDATE_TRIGGER was introduced at this commit here Add a random jitter to target state polls, and a config var to ignore… · balena-os/balena-supervisor@8f07bf6 · GitHub and it only really targets the case with network overload with many devices on the same network. It does not really speed up updates in any way. The name is maybe a bit misleading.
Thanks,

I also created an internal docs issue for improving the documentation regarding this.
