I guess you could install cockpit (via Terminal, sorry, but it’s pretty straightforward and there are good guides). After that, you could use the cockpit web interface to deploy docker/podman containers. It’s a bit clunky sometimes, but it does the job purely in UI.

You can also manage updates, backups, etc via cockpit if you install the required modules.

As base, I’d use any stable Linux distro that’s reccomended for server use.

Edit: Comment was in wrong place, refiled as op level comment.

Sure, that’s why I use it. My point was more that improved battery performance, at least to that degree, is a your-specific-usecase thing, not a Graphene thing.

Makes sense, but with that setup, a different custom rom on a phone with better life would deliver even better results.

I like my pixel, I like Graphene, but I still feel battery is a weak point.

Show me a Pixel with two days of battery life with heavy use. My 8a lasts about a day, sometimes less. Similar reports for a friends 8a and my brother’s 7a.

That looks very Plan9. I now want a Plan9 Smartphone.
