The Sortix Operating System =========================== Sortix is a small self-hosting Unix-like operating system developed since 2011 aiming to be a clean and modern POSIX implementation. There's a lot of technical debt that needs to be paid, but it's getting better. Traditional design mistakes are avoided or aggressively deprecated by updating the base system and ports as needed. The Sortix kernel, standard libraries, and most utilities were written entirely from scratch. The system is halfway through becoming multi-user and while security vulnerabilities are recognized as bugs, it should be considered insecure at this time. Links ----- For more information, documentation and news, please visit the official website: https://sortix.org/ You can also download the newest release and cutting edge nightly builds at: https://users-cs.au.dk/sortie/sortix/release/ You can retrieve the current git master from our project page at: https://gitlab.com/sortix/sortix System Requirements ------------------- Sortix has low system requirements. It also works well under virtual machines such as VirtualBox and Qemu: * A 32-bit x86 (with SSE) or 64-bit x86_64 CPU. * A few dozen megabytes of RAM - or if you are using a cdrom release with ports then you likely need at least twice the size of the cdrom image. * A harddisk or cdrom drive or support for booting from USB. * A multiboot compliant bootloader if booting from harddisk. * ATA or AHCI harddisk. Documentation ------------- The system is documented as manual pages. Introductory system usage is covered in the user-guide(7) manual page. Building Sortix --------------- Development of Sortix under itself is covered in development(7). Development from another operating system is covered in cross-development(7). You can view the cross-development(7) manual page with this command: man share/man/man7/cross-development.7 License ------- Copyright(C) Jonas 'Sortie' Termansen and contributors 2011, 2012, 2013, 2014, 2015, 2016.
