It was a joke about the fact that PostmarketOS considers only QEMU a “main” device. Every real phone is in the “community” section because they’re too buggy. So the only good device to run that OS on is a virtual one running inside your desktop.
If you want all drivers in the mainline kernel, you clearly cannot handle the software on your own. The reason why linux phones suck are the drivers that are either bad or don’t exist. The desktop (or palmtop I guess) environments are pretty usable if you run it on something with good drivers (like QEMU - my favorite phone).
I used to selfhost on a core 2 duo thinkpad R60i. It had a broken fan so I had to hide it into a storage room otherwise it would wake up people from sleep during the night making weird noises. It was pretty damn slow. Even opening proxmox UI in the remotely took time. KrISS feed worked pretty well tho.
I have since upgraded to… well, nothing. The fan is KO now and the laptop won’t boot. It’s a shame because not having access to radicale is making my life more difficult than it should be. I use CalDAV from disroot.org but it would be nice to share a calendar with my family too.
