The penguin kernel is indeed very nifty and boots nearly everywhere. Most importantly it is replete with battle-tested drivers.

Maybe the bold solution would be to port the Serenity userland + UI stack across to Linux and be very staunch about what gets into it. Essentially grafting the Linux kernel in place of the Serenity one, and using its UI Kit and WindowServer instead of GTK/QT/X/Wayland.

Maybe it might even be possible to preserve the logic and non-UI libraries of many applications, even if the UI required a complete rewrite.

A bit fantastical but just putting it out there.
