DragonFly BSD is a free, Unix-like operating system which was forked from FreeBSD 4.8. Matt Dillon, a long-time FreeBSD and Amiga developer, started work on DragonFly BSD in June 2003 and announced it on the FreeBSD mailing lists on July 16, 2003 [1].
Dillon started DragonFly in the belief that the methods and techniques being adopted for threading and SMP in FreeBSD 5 would lead to a poorly performing system that would be very difficult to maintain. Intended to be "the logical continuation of the FreeBSD 4.x series", DragonFly is being developed in an entirely different direction from FreeBSD 5, including a new Light Weight Kernel Threads (LWKT) implementation and a light weight ports/messaging system. Many concepts planned for DragonFly were inspired by AmigaOS.
