‘mostly open source’? I’m intrigued…

Yea. That is THE one reason why I’d never touch GrapheneOS as long as it only runs on Pixel hardware.

I don’t see LibreCMC (https://librecmc.org/) mentioned anywhere in this thread, so correct that.

Unlike Open WRT, LibreCMC is recognised by GNU to be a fully free Linux distribution, and you still get the time-honoured LuCi web administration interface.

LibreCMC runs on much fewer devices as OpenWRT, which can be a feature for those who are overwhelmed by the length of OpenWRT’s list.

WTAFF is that supposed to be anyway?

What is the authoritative source of information for learning how to run an instance of peertube and how difficult is it for a moderately skilled sysadmin to do so?
