You can see the talk.
The goal of GNOME OS are:
- provide a working base for development, design, and user testing
- automate QA from boot, to installation, to session
- provide a VM for marketing and outreach purposes
- provide a minimum viable product for OEMs and OSVs using GNOME on their devices
The explicit anti-goal is to create yet another Linux distribution.
We don’t have the resources for handling hardware enablement and security updates. At most, GNOME can provide a place upstream where to submit hardware enablement involving GNOME components, and host shared security fixes, instead of bottling them into downstream silos; but that’s not really up to us to decide.
