| | FreeBSD - Wikipedia, the free encyclopedia |
 | | The kernel, device drivers and all of the userland utilities, such as the shell, are held in the same source code revision tracking tree (CVS). |
 | | This is in contrast to Linux, a similar but better-known operating system, in which the kernel is developed by one set of developers; userland utilities and applications by others, such as the GNU project; and all are packaged together by other groups and published as Linux distributions. |
 | | An extensible mandatory access control framework (the TrustedBSD MAC Framework), filesystem Access Control Lists (ACLs), and the new UFS2 filesystem all came from TrustedBSD. |
