Chapter 17. General Updates

Matahari
Matahari in Red Hat Enterprise Linux 6.2 is fully supported only for x86 and AMD64 architectures. Builds for other architectures are considered a Technology Preview.
Automatic Bug Reporting Tool
Red Hat Enterprise Linux 6.2 introduces ABRT 2.0. ABRT logs details of software crashes on a local system, and provides interfaces (both graphical and command line based) to report issues to various issue trackers, including Red Hat support. This update provides the following notable enhancements:
  • More flexible configuration with a new syntax.
  • Out-ouf-process plugins (plugins run in separate processes and communicate via inter-process communication with other processes). Advantages of such a design are:
    • bugs in plugins do not break the main daemon,
    • more secure as most of the processing is now done under the normal (non-root) user,
    • plugins can be written in any programming language.
  • Reporting backend is shared across all of Red Hat's issue reporting tools:
    • ABRT, sealert, all users of python-meh (Anaconda, firstboot)
    • Because all of the tools above share the same configuration, it only has to be written once.
