Non-goals
Does not have to support the runtime installation of kernel modules. This will prevent the out-of-the-box installation of, for example:
- Proprietary NVIDIA kernel driver (NVIDIA GPUs must either be new enough to use the open-source kernel modules that can be distributed in-tree, or else use Nouveau)
- VirtualBox (requires out-of-tree modules; QEMU/KVM probably do a better job anyway)
- Vendor-specific VPNs that require custom out-of-tree kernel modules that cannot be redistributed with the kernel due to license incompatibility
Does not have to support the use case of developing low-level system components like the kernel, drivers, systemd, etc., as this can be troublesome with an immutable base OS.
Does this part mean there will also be no support for ZFS?
Yes I am involved in the project. As for not worrying about large system upgrades, things break, no matter how much testing you do on them. For running KDE I prefer to run the latest, it has the least bugs and the newest features.
There will be at minimum 3 editions of this OS, one for developers and those who love to live on the bleeding edge, one for enthusiasts and one for general users. The one for general users will be well tested and aim to have zero showstopping bugs.
