If we're going to write RustBSD, why not RustMinix -- and get the benefits of microkernel design? Isn't it about time we give up a few percent performance for robustness?
A person could reasonably argue that this is redox. It's different in that it's a new OS rather than a rust-ified version of an existing thing, but still, it's a microkernel unix-ish OS in rust.
What I care about is getting an interactive shell prompt and a filesystem with . and .. and / and BOURNE shell compatible semantics, and an ability to run vi and emacs. (I am less sure plan9 people care about shell btw they went rc and then into some place I don't understand up in the 5th dimension)
MINIX is dead for multiple reasons, including technical ones [1]. Simply put, its design and implementation are no longer fit for purpose on modern systems. At this point, starting over from scratch would probably be more effective than trying to address all of its issues.
