What is Fedora?

Fedora is a set of projects sponsored by Red Hat and guided by contributors. These projects are developed by a large community of people who strive to provide and maintain the very best in free, open source software and standards. The center piece of the Fedora project is an operating system that is released twice a year, and is based on the Linux kernel, that is always free for anyone to use, modify, and distribute.

Formal Announcement

What Is The Alpha Release?

The Alpha release provides the first opportunity for the wider community to become involved with the testing of Rawhide. The Alpha release represents a sanitized snapshot of Fedora's development branch, which sees rapid changes and will become the next major release. It should boot on the majority of systems, shows some of the new features that will be included in the next release, and gives testers an opportunity to provide feedback and bug reports to help ensure that the next release is as good as possible.

You can find the official release announcement here.

How To Try Alpha

Thanks to the infrastructure that was developed during the Fedora 7 release cycle, Alpha is accompanied by installable live CDs of both the GNOME and KDE desktops. With a Live CD users can perform testing and demonstration without installing any software to the hard disk. As the Alpha release is largely targeted at developers and contains many bleeding edge packages, this is the best method for less experienced users who want to get involved with testing. The Live CDs also have an option to install Fedora to the hard disk for the more intrepid users.

The best way to download Fedora 10 Alpha is through BitTorrent -- visit the Fedora torrent server for a listing of available images.

Alpha images can also be downloaded from any of our mirrors. Remember that live images can be used on USB media via the livecd-iso-to-disk utility available in the livecd-tools package on existing Fedora systems. Refer to the USB How-to for more instructions.

You can also use Jigdo to download the i386, x86_64, or ppc versions.

No Split Media Available
There are no split-media CD installation sets of Fedora 10 Alpha available. This is a known issue and is already being worked on.

Release Overview

As always, Fedora continues to develop and integrate the latest free and open source software. The following sections provide a brief overview of major changes from the last release of Fedora. For more details about other features that are making their way into Rawhide and set for inclusion in Fedora 10, refer to their individual wiki pages that detail feature goals and progress. Also, throughout the release cycle, there are interviews with the developers behind key features giving out the inside story.

Features for this release are tracked on the feature list page.


Fedora 10 Alpha features the development version of GNOME 2.23 and the KDE 4.1 release. In addition to that, the following are major features targeted for this release.


RPM 4.6

  • Features/RPM4.6 -- Update RPM to 4.6, which includes many enhancements and bugfixes.

Boot up

The graphical boot up system used in previous Fedora versions is being replaced with a new system called Plymouth. There are a few issues with Plymouth in the Alpha:

  • The graphical boot splash screen that comes with Plymouth requires kernel mode setting drivers that are not shipped in the Alpha. To see the graphical plugin before the drivers land in rawhide, add vga=0x318 to the kernel grub command line. This uses vesafb, which won't necessarily give you the native resolution for your flat panel, and may cause flickering or other weird interactions with X. Without vga=0x318, Plymouth uses a text-based plugin that is plain but functional.
  • Plymouth hides boot messages. To view boot messages, press the [Esc] key during boot, or view them in /var/log/boot.log after boot up.
  • If you mistype your password on your encrypted root filesystem, Plymouth crashes quietly, giving no indication what went wrong. This is a known issue that is fixed post-Alpha.
  • Plymouth doesn't behave well with fsck and maintenance mode login shells in the Alpha.
  • Plymouth has other assorted problems. It can be disabled by removing rhgb from the kernel command line.

Security audit

  • Security Audit -- A new security audit system and intrusion detection system that includes a new UI, libraries, and tests.

Kernel 2.6.27 development version

Fedora 10 Alpha includes a development snapshot of the 2.6.27 kernel. More details at


Objective CAML (OCaml) coverage greatly extended

Improved Haskell support

  • Haskell support -- provide good support for Haskell development and use, with a high number of quality libraries and tools available.
