Enter Maestro, a unix-like monolithic kernel that aims to be compatible with Linux in order to ensure wide compatibility. Interestingly, it is written in Rust. It includes Solfége, a boot system and daemon manager, maestro-utils, which is a collection of system utility commands, and blimp, a package manager. According to Luc, it’s creator, the following third-party software has been tested and is working on the OS: musl (C standard library), bash, Some GNU coreutils commands such as ls, cat, mkdir, rm, rmdir, uname, whoami, etc… neofetch (a patched version, since the original neofetch does not know about the OS). If you want to test it out, fire up a VM with at least 1 GB of ram.
Mentioning it’s written in rust should imply this code base will have secure concurrency, better memory handling, be easier to extend, while maintaining near C++ performance. None of these are guarantees, but considering so many rust projects are “C/C++ programs, rewritten” it seems worth calling out as a differential. The language’s advantages extending to the kernel make it an interesting project.
