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.

GNOME upstream tracker

Ubuntu tracker

Debian tracker

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:

  • yum erase hal-libs
  • 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.

Documentation

N/A

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.
