'''9front''' is a [[fork (software development)|fork]] of the [[Plan 9 from Bell Labs]] [[operating system]]. The project was started to remedy a perceived lack of devoted development resources inside [[Bell Labs]], and to integrate many changes that were made to Plan 9 independently. It has accumulated various fixes and improvements, including greatly expanded hardware support.

== Description ==
{{main|Plan 9 from Bell Labs}}
9front retains features of Plan 9 from Bell Labs and continues to integrate changes from the original source tree while adding new drivers, features and bugfixes.<ref name="features" /> As with stock Plan 9, 9front is a [[free software]] [[distributed operating system]] that achieves resource generalization by using the [[9P]] protocol to present a consistent interface for accessing local and remote resources as files. It also features private [[namespace]]s,<ref name="namespaces" /> [[union mount]]s, [[procfs|proc]] file system, and native [[unicode]] support throughout the system.

== History ==
Work on the [[fork (software development)|fork]] began in March 2011.<ref name="began" /> The project was announced under the name "Plan 9 from The People's Front of Cat-v.org",<ref name="nt-init" /> though subsequently it was referred to by the name "9front".<ref name="osnews-init" />

== Development ==
The project is hosted on [[Google Code]];<ref name="plan9front-project">{{cite web|title=plan9front Project Home|url=https://code.google.com/p/plan9front/|accessdate=28 September 2014}}</ref> unlike Bell Labs' distribution, 9front uses [[Mercurial]] for [[source code]] [[revision control]].<ref name=plan9front-checkout>{{cite web|title=Source Checkout – plan9front|url=https://code.google.com/p/plan9front/source/checkout|website=Google Code|accessdate=28 September 2014}}</ref> Like Plan 9, 9front is written in C using Plan 9 extensions,<ref>{{cite web|title=C Programming in Plan 9 from Bell Labs|url=http://doc.cat-v.org/plan_9/programming/c_programming_in_plan_9|website=cat-v.org|accessdate=18 October 2014}}</ref> which are supported by Plan 9's custom compilers. Additionally, [[GNU Compiler Collection|GCC]] supports most of Plan 9's C dialect, while [[Clang]] has only rudimentary support.<ref>{{cite web|title=Begin implementing Plan 9 C extensions.|url=http://reviews.llvm.org/D3853|website=LLVM Reviews|accessdate=18 October 2014}}</ref>
