I said they’re experimenting with Windows simply being a desktop environment on top of Linux. Only the Linux kernel would be involved. NTOSKRNL wouldn’t be present. I suspect if they’re trying to get native Windows apps to run, some call translation layer would have to exist (similar to what WINE provides).

Perhaps it is a bold claim, I haven’t seen it first hand. And it certainly has me hoping it goes much further than experimentation. I’d love to have a Windows environment on top of ext4 or zfs and the Linux kernel.
