￭ By default, it's historically accessible;
￭ Queueless incremental mirroring, master to multi-slave;

The DragonFly BSD CDs are Live CDs, but an installer is included, which can be run via console, or from a web browser. To activate the installer, boot the CD and login with the user 'installer' (no password). DragonFly BSD is a BSD powered operating system based on the same UNIX ideals and APIs as the BSD and Linux OSes. It gives the BSD base a chance to grow in an entirely different direction from the one taken in the NetBSD, OpenBSD and FreeBSD operating system.
