Linux maintainers are unwilling to get rust into the kernel, so some rust folks decided to start writing a new kernel with same ABI. This allows them to make new architectural decisions. An example being their “frame kernel” (something between a monolithic kernel and a microkernel).
If I may say, it’s more legible and the tooling is way better, right off the bat.
Good, this is a great way to direct that energy and help Rust mature without breaking a working OS.
That’s the spirit. I see some good arguments for and against Rust in Linux. It’s just more complicated than »do it« or »don’t do it«.
Well at least this time I’m not getting dogpiled by a bunch of Rust fanatics.
