From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The kernel is probably too large to rewrite the whole thing at once. This could lead to a future without any new C kernel devs, leading to stagnation, while the Rust kernel could be many years away from being finished. (Assuming we actually move away from C.)
At that point you might as well just start an entirely new kernel and hope it is good enough to eventually replace the Linux one once all devs are gone. Kinda the X11 and wayland thing.
You can very safely remove the "probably" from your first sentence.
the number I saw floating around was 3 years to production useful. regardless, C's end days as the go-to, large systems level language are drawing nigh.
edit: tear
I think this number is overblown. Production useful doesn't have to mean 1:1.
Running it without all graphics drivers would be fine for server use. Also, not all filesystems need to be ported: basic ones should be enough for start. But not only servers, home routers run Linux kernel...
If every OEM starts contributing their drivers in rust, this could move quickly...
