Has anyone here tried to run GRUB on their Librem 5? It seems like GRUB might serve the same purpose as Titanium backup does on an Android phone. If that works, then perhaps the next step would be to put Android AOSP on to the phone as a second OS (with PureOS still there also). So you install Android too, and then Google the Android up with everything Google needs for any app to authenticate and run correctly. The idea would be to run the phone in PureOS most of the time. But when you need a banking app or some kind of app that won’t run under PureOS, you reboot the phone in to Android and use the apps that you need there before switching back to PureOS. You switch back to PureOS with only a reboot. The benefit would be that PureOS could remain completely pure and uncompromisingly safe for privacy and security, no exceptions what-so-ever in PureOS, to security when you need to obtain any and all of a Googled phone’s functionality. You would then temporarily leave PureOS to get full authentication by Google when needed, in their eco-system too. It becomes a place for very short visits, but not where you live.
In such a configuration, Google and all of Google’s advertisers might only see you for just a few minutes once per day, once per week, or once per month. All they’ll know about you then is what they can get from your few minutes using only a few apps before you disappear again to a place that can not be tracked and spied on. So you disappear for a long time again before you can create or communicate any substantive history there. They also get nothing from your use of PureOS, which is where you are most of the time. But to get this to work, the Librem 5 would need the ability to run a fully Googled instance of Android. Has anyone here got that working yet?
