A few of my friends experienced the glory of PiHole in my home network and asked, if I could install such a thing in their networks as well.

Which I obviously could, but none of them are interested in updating/maintaining such a device. So I would like to collect some suggestions on how to deploy such a box with (ideally) zero interaction from my side until the end of times.

My hardware platform of choice would be a cheap thin client (Futro s920 or something like that) running Ubuntu with unattended updates enabled.

Pihole itself seem to offer an auto-updater, but I’m not sure how stable that runs in the long run - maybe Docker would be better suited here?
