DragonFly BSD v2.0.1

What is DragonFly BSD?

DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series.

It is our belief that the correct choice of features and algorithms can yield the potential for excellent scalability, robustness, and debuggability in a number of broad system categories. Not just for SMP or NUMA, but for everything from a single-node UP system to a massively clustered system. It is our belief that a fairly simple but wide-ranging set of goals will lay the groundwork for future growth. The existing BSD cores, including FreeBSD-5, are still primarily based on models which could at best be called 'strained' as they are applied to modern systems. The true innovation has given way to basically just laying on hacks to add features, such as encrypted disks and security layering that in a better environment could be developed at far less cost and with far greater flexibility.

We also believe that it is important to provide API solutions which allow reasonable backwards and forwards version compatibility, at least between userland and the kernel, in a mix-and-match environment. If one considers the situation from the ultimate in clustering... secure anonymous system clustering over the internet, the necessity of having properly specified APIs becomes apparent.

Finally, we believe that a fully integrated and feature-full upgrade mechanism should exist to allow end users and system operators of all walks of life to easily maintain their systems. Debian Linux has shown us the way, but it is possible to do better.

DragonFly is going to be a multi-year project at the very least. Achieving our goal set will require a great deal of groundwork just to reposition existing mechanisms to fit the new models. The goals link will take you to a more detailed description of what we hope to accomplish.

September 27, 2008 - The DragonFly-2.0.1 Release is ready!

DragonFly CDs are 'live', which means that the CD will boot your system and let you log in as root (no password). You can use this feature to check for hardware compatibility and play with DragonFly a little before actually installing it on your hard drive.

The CD includes an installer that can be run at the console, or (experimentally) via a web browser. Make sure you read the README file for more information. To activate the installer, boot the CD and login as 'installer'.

The installer has a Netboot server option. You can boot the CD on one machine, enable the feature via the installer, and then PXEBoot other systems and do a network based install. System operators should be aware that running the netboot server hardwires a 10.1.0.X network and runs a DHCP server which might interfere with other DHCP servers on your LAN.
