Attended sysupgrade - don't keep config

[adsbenham]

I've done a couple of attended sysupgrades. Now I need to do one in which I don't preserve the config, but I don't see a luci option or an auc argument to specify whether to keep the config or not.
And I don't remember seeing an option on the attended sysupgrades I've done before. Is it an option which will appear as part of the upgrade process ?

I'm trying to upgrade my Netgear R7800 to 24.10.0 from 23.05.5, but not getting further than an "Impossible package selection" at the moment - maybe the "keep config" question comes later ?

Ah, now the "Impossible package selection" has gone away, I see how it works.

The upgrade preparation reports that the config should not be preserved, and at the point where one is asked whether to go ahead one is asked whether to preserve the config.
