Attended Sysupgrade seems like the solution for this. It looks at your packages, does a cloud build for your board with your packages and you can push a button to update.

Be aware if you're on snapshot, that the packaging situation is iffy right now. opkg is being replaced with apk, and there's some rough edges. I had a sysupgrade build that ended up with neither package manager, and the automatic tool doesn't currently work for doing new builds from an apk system.

My wishlist item would be less churn or at least replacements should integrate as well as the old version.

Thanks, I wasn't aware of that package. I'll try it out. It should definitely be added to the default install once the devs are satisfied that it is stable.
