GoKawiilHobby OS Moxnox hits version 1.0 with NT-style design and Btrfs support
Moxnox 1.0, a hobbyist operating system modeled on Windows NT's syscall design but POSIX-compatible, has been released for amd64 and aarch64 architectures. The roughly 130,000-line C++ project includes a GNU base system, can run on the Btrfs filesystem, and is mature enough to self-host, meaning it can compile itself. The developer notes the Btrfs implementation works for basic use but warns against mounting anything beyond disposable test filesystems.
