HAL Removal

Summary

HAL is a behemoth, do-it-all, daemon to access hardware. It is now obsoleted by Package-x-generic-16.pngudisks and Package-x-generic-16.pngupower, as well as libudev for device discovery.

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, Package-x-generic-16.pnghal package maintainer deprecated it for Fedora 16, and later it was also blocked from composes. So this feature is tracking 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,http://download.fedoraproject.org/pub/fedora/linux/development/rawhide/i386/os/ --repoid=fedora-rawhide-i386 --qf '%{NAME}' --whatrequires hal hal-devel hal-info hal-libs hal-storage-addon | sort -u

Package-x-generic-16.pnggnome-vfs2 done GnomeVFS has been deprecated since 2008, applications should use Package-x-generic-16.pnggvfs instead. Since >80 other packages still depend on gnome-vfs2, its HAL support was disabled (Fedora bug 698638), as was recently done also by Debian (Debian bug 599020), but the goal is to get rid of GnomeVFS too.

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 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

Dependencies

  • See description

Contingency Plan

  • Undeprecate hal.

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.
