Halsectomy
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 David Zeuthen's and Kay Siever's summaries of plans.

libgphoto2 camera handling |
needs tagging as libgphoto device (patch sent and committed); (discussion); udev-extras auto-acl management fixed as well; libgphoto2_port/disk/disk.c falls back to /etc/mtab reading without hal, which is functionally equivalent |

Rhythmbox uses gudev now. Karmic package needs upgrade to 0.12.4 version |

GNOME power management |
g-p-m uses DeviceKit-power now, but backlight handling still require hal when the backlight is not a xrandr device. All the X drivers need to support XBACKLIGHT before we can turn it off completely. Intel do, nouveau sortof does, so we could disable HAL in g-p-m using a #ifdef if we're sure the drivers support backlight |
