Hi all, I have a Netgear D7800 that I have run openwrt on for a long time. Does anyone else have one (or similar) and how do I get sysupgrades working? They error out when I upload a sysupgrade image, with an error about unsupported partition layout.

But as far as I can tell, I have a v2.0 layout, as I flashed a factory openwrt image manually. Is sysupgrade just not supported at all anymore (and if so, why do the images still exist?), or do I need to do something to reenable it?
