HAL Removal


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.

Current status

  • Targeted release: Fedora 16
  • Last updated: 2011-07-12
  • Percentage of completion: 93%

This feature originally proposed the removal of HAL from the Fedora Desktop spin. This goal has already been accomplished and we also completed the removal from the Fedora DVD. In the meantime, hal package maintainer deprecated it for Fedora 16, and later it was also blocked from composes. So, unless somebody volunteers to maintain it again, this feature will track the complete removal of HAL from the distribution.

Detailed Description

To generate the list of packages still depending on hal in rawhide:

$ repoquery --repofrompath=fedora-rawhide-i386, --repoid=fedora-rawhide-i386 --qf '%{NAME}' --whatrequires hal hal-devel hal-info hal-libs hal-storage-addon | sort -u

Benefit to Fedora

Faster boot-up, and removal of obsoleted technology.


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 remove hal-filesystem 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


  • See description

Contingency Plan

  • Undeprecate hal.



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.
