HAL Removal
Summary
HAL is a behemoth, do-it-all, daemon to access hardware. It is now obsoleted by udisks (né DeviceKit-disks) and upower (né DeviceKit-power), as well as libudev for device discovery.
This feature tracks the removal of HAL in the Fedora Desktop spin.
See also:
Note that gnome-vfs2 still relies on HAL, and is dragged in through libgnomeui. So removing the gnome-vfs2, or libgnomeui dependencies from applications also helps towards that goal.

Benefit to Fedora
Faster boot-up, and removal of obsoleted technology.
Scope
Loads of applications require HAL itself, or libhal. Applications should not rely on HAL, or libhal being available.
How To Test
Need to test:
- rpm -e hal or yum erase hal
- Check that nothing gets removed because it depends on hal
- Check that applications that access hardware still work as before
User Experience
- Faster boot-up
- Possibly faster applications startup when switching from libhal to libgudev for device enumeration
Dependencies
- See description
Contingency Plan
- Still ship HAL. If the last thing that depends on hal is gnome-power-manager for the backlight support, we can stop running hal as a service at boot and make it dbus-activated instead.

Release Notes
- Fedora now does not ship with the HAL daemon, and libhal by default. If a specific application require libhal to function, please file a bug against it to be ported to the new technology.
