But social circles do contain the occasional Linux nerd such as myself. However, I can not provide all of the hardware. Especially since RAM has become unaffordable thanks to our good friend Sam Altman. But what if I do not have to? What if people would scavenge their drawers for their old smartphones and hand it to me to provide the hardware to host their services on? | But social circles do contain the occasional Linux nerd such as myself.

Here in Europe, people are looking for ways to ditch US-tech. This includes family and friends of mine. And there are plenty of alternatives such as NextCloud and Immich. Thing is, software nowadays is run as a service and the typical friends and family should not be expected to know how to administrate a Linux server.

Hardware
I gathered a couple of old Android phones to test this scheme with.
OnePlus 6
I got this one for € 50. Flashing was trivial and it seems to run well. The standard PostmarketOS kernel lacks some kconfig flags to support docker, so I had to compile a custom kernel.
Fairphone 3
This phone was free because it was completely broken. On a hunch, I attempted to reflow the SoC with the hot-airgun which made it come back to life. Flashing PostmarketOS was also super easy. Also needed kconfig tweaking to get Docker to work.
OnePlus 8 Pro
Has some cracks in the screen and case which reduced the price to a mere € 40.
TOOD: flash to PMOS.
Upstream?
kconfig
It would be handy to enable the kconfig options for docker/k3s by default. TODO: Ask the PostmarketOS people whether this is desirable.
containerd
Containerd fails to start because of a misconfigured path. Would be handy to fix upstream in either Alpine or PostmarketOS, whichever ships this mistake.
