Obtaining DragonFly 2.2.x for your system

2.2 ISO Images for CDs

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.

2.2.x Release Errata

DragonFly releases are meant to be stable, dependable entities. We backport compatible bug fixes from current development into release branches but we do not generally backport new features. The release CD is always a '.0', e.g. 2.2. The most common way to track a release is to use cvsup to track the release sources and then build and install a new world and kernel to keep your system updated.

We do not always get every last little fix into a release. Please be sure to read the errata page for the release CD!
