Earlier quoted context omitted.
I have scripted this (well, installation of some systemd units, but the workflow is the same). So I just plug my tablet into my laptop and run my script every time it updates. It’s not ideal, but not super tedious either. I’ve been planning to start charging via a raspberry pi so that the pi can automatically tend to the device whenever it’s connected, but haven’t gotten there yet.
Why not script it over ssh (wifi), preference or is not as simple as I imagine? (never used one but the ability to get shell and be able to rsync files is one of the reasons I consider a remarkable). I could be misinformed though, haven't researched it a lot.
Updates can be deferred, so the process isn’t too disruptive.
Edit: oh, yeah I see what you’re getting at. That direction could work, and I used to do that years ago, as it turns out, but these days I am frequently not on a familiar WiFi network when I’m using the tablet, so cabling has been more practical.
