#title Halsectomy: The Deprecation of HAL

== Summary ==

Hal is in the process of being deprecated, since it has become a large
monolithic unmaintainable mess, and also duplicates a lot of functionality
which are nowadays provided by udev and the kernel itself. Please see
[[http://lists.freedesktop.org/archives/hal/2008-May/011560.html|David Zeuthen's]] and
[[http://lists.freedesktop.org/archives/devkit-devel/2009-April/000140.html|Kay Siever's]]
summaries of plans.
