### Advantages over Linux
* More control
* You can easily build your own base system / release / live cd.
* The rpm based distros lack that.
-* Everything is developed in CVS. And the CVSROOT is available, so that you can download it and commit to your own repository.
+* Everything is developed in GIT. And the GIT repository is available, so that you can download it and commit to your own repository.
* Guaranteed to build from source
* [jail(2)](http://leaf.dragonflybsd.org/cgi/web-man?section#2&commandjail) support
* A jail is a [chroot(2)](http://leaf.dragonflybsd.org/cgi/web-man?section#2&commandchroot) on steroids with low overhead.
