Writing a Unix clone in about a month

The creator of Bunnix, a Unix-like operating system for x86_64 targets, spent 27 days working on the project. The kernel is primarily written in Hare and includes drivers for PCI, AHCI block devices, PS/2 keyboards, and more. Bunnix also features third-party software like Vim, gzip, and tcc, with a libc derived from musl libc.
