I had question how to set updates to manual because my wifi was detected as unmetered but it is limited. Here is only one option to disable System Updater app. It works i can now control when to install update. Of course i wanted to have notifications about updates but it is beter than force update.
I was thinking how exactly working Auto updates?
If is here unmetered wifi could smartphone download at lockscreen download update -> Install it when at lockscreen and then auto reboot / manual reboot will it boot to new system partition?
Teoreticaly if someone will have right signing keys and host self update server at local network + DNS resolve to this update server with self compiled system. Will smartphone with grapheneos install this custom os automatically at lockscreen?
