Well, I though, I have a Raspberry Pi, why not figure out how to run Freedom Box on RPi?
1 hour later I've bricked my Pi, not anything to do with Freedom Box, just because apt upgrade failed at an important moment and anyway now it's a Raspberry Brick.
I decided to buy the FreedomBox hardware (which is open source, btw) server and it arrived less than 24 hours after I ordered! ^_^
So far the hardest thing has been remembering to turn off the VPN when trying to access local network devices...
