The Redox OS, written in Rust and currently under development, is only "a few months of work away" from self-hosting, meaning that the Rustc compiler would run on Redox itself, according to its creator Jeremy Soller.

Soller, who is also a principal engineer at the Linux hardware company System76, based in Denver, USA, says that he is now running Redox OS permanently on one of his company's laptops, with "full support for the keyboard, touchpad, storage and Ethernet".
