 Being a derivative of FreeBSD , DragonFly has inherited an easy @-@ to @-@ use integrated build system that can rebuild the entire base system from source with only a few commands . The DragonFly developers use the Git version control system to manage changes to the DragonFly source code . Unlike its parent FreeBSD , DragonFly has both stable and unstable releases in a single source tree , due to a smaller developer base .
