Welcome to Fedora
Fedora is a Linux-based operating system that showcases the latest in free and open source software. Fedora is always free for anyone to use, modify, and distribute. It is built by people across the globe who work together as a community: the Fedora Project. The Fedora Project is open and anyone is welcome to join. The Fedora Project is out front for you, leading the advancement of free, open software and content.
You can help the Fedora Project community continue to improve Fedora if you file bug reports and enhancement requests. Refer to http://fedoraproject.org/wiki/BugsAndFeatureRequests for more information about bugs. Thank you for your participation.
To find out more general information about Fedora, refer to the following Web pages:
- Fedora Overview (http://fedoraproject.org/wiki/Overview)

New in Fedora
This release includes significant new versions of many key components and technologies. The following sections provide a brief overview of major changes from the last release of Fedora.
Spins
Fedora includes several different spins. Spins are variations of Fedora built from a specific set of software packages. Each spin has a combination of software to meet the requirements of a specific kind of end user. In addition to a boot.iso image for network installation, users have the following spin choices:
- A regular Fedora image for desktops, workstations, and server users. This spin provides a good upgrade path and similar environment for users of previous releases of Fedora.
- One of several Live images that can be run from a disc or USB flash device, and can be installed to hard disk as desired. Refer to the Live section for more information about the Live images.
More custom spins are available at http://spins.fedoraproject.org. These Live images can be used on USB media via the livecd-iso-to-disk utility available in the livecd-tools package.
Jigdo
Fedora releases are also available via Jigdo. This distribution method can improve the speed of obtaining the installation ISO images. Instead of waiting for torrent downloads to complete, Jigdo seeks the fastest mirrors it can find via the Fedora Project Mirror Manager infrastructure, and downloads the bits it needs from these mirrors. To optimize seeking these bits, you can tell Jigdo to scan a DVD or CD you already have, and cut down on redundant downloads. This feature becomes particularly useful if you:
- Download all the test releases and then get the final release, in which case you have 90% of the data already with each subsequent download.
- Download both the DVD and the CD set, in which case the DVD holds 95% of the data needed for the CD sets.
- Download any combination of the above.
Upgrading using PreUpgrade
PreUpgrade is an application users run on an existing Fedora 7, 8 or 9 installation, that resolves and downloads packages required to upgrade Fedora. While PreUpgrade downloads the necessary packages, users are free to continue using their systems.
To use PreUpgrade to upgrade Fedora 9 to Fedora 10:
- Back up all important data before upgrading.
- Run the
yum updatecommand as root to make sure all packages are updated to their latest versions. - Run the
yum install preupgradecommand as root to install PreUpgrade. - Run the
preupgradecommand as root to start the PreUpgrade application. - Select Fedora 10 (Cambridge) on the Choose desired release screen, and click the Apply button.
- When all of the packages have downloaded, reboot your system to start the Fedora 10 installer.
For further information, refer to the PreUpgrade Wiki
Features
- This release features GNOME 2.24.
- KDE 4.1.2 is available in the KDE Live image as well as the regular DVD.
- Xfce 4.4.2 is available as part of this release.
Road Map
The proposed plans for the next release of Fedora are available at RoadMap.

Installation Notes
Anaconda is the name of the Fedora installer. This section outlines issues related to Anaconda and installing Fedora 10.
Anaconda tests the integrity of installation media by default. This function works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. The Fedora Project recommends that you test all installation media before starting the installation process and before reporting any installation-related bugs. Many of the bugs reported are actually due to improperly-burned CD or DVDs.
The mediacheck function is highly sensitive and may report some usable discs as faulty. This result is often caused by disc writing software that does not include padding when creating discs from ISO files. To use this test, at boot time hit any key to enter the menu. Then press the [Tab] key, add the option mediacheck to the parameter list, and press [Enter] .
After you complete the mediacheck function successfully, reboot to return the system to its normal state. On many systems this results in a faster installation process from the disc. You may skip the mediacheck option when rebooting.
To perform memory testing before you install Fedora, press any key to enter the boot menu, then select Memory Test. This option runs the Memtest86 standalone memory testing software in place of Anaconda. Memtest86 memory testing continues until you press the [Esc] key.
Fedora 10 supports graphical FTP and HTTP installations. However, the installer image must either fit in RAM or appear on local storage, such as the installation DVD or Live Media. Therefore, only systems with more than 192MiB of RAM or that boot from the installation DVD or Live Media can use the graphical installer. Systems with 192MiB RAM or less fall back to using the text-based installer automatically. If you prefer to use the text-based installer, type linux text at the boot: prompt.
Changes in Anaconda
- Built-in support for resizing ext2, ext3, and ntfs partitions.
- Support for installation to encrypted block devices, including the root filesystem.
- Consolidated network booting ISO image, replacing old
boot.iso,diskboot.img, andrescuecd.iso. - Second stage installer location now independent of software package location.
- Native installation to x86 and x86_64 machines using EFI and booting via
grub. - Hardware probing and detection now based on HAL and
udev. - Support for persistence in Live images on USB flash media.
Installation Related Issues
- When PXE booting and using a .iso file for the installation media via NFS you are now required to add method=nfsiso:server:/path to the command line.
IDE Device Names
Use of /dev/hdX on i386 and x86_64 for IDE drives changed to /dev/sdX in Fedora 7. If you are upgrading from an earlier version than Fedora 7, you need to research about the importance of labeling devices for upgrades and any partition limitations.
IDE RAID
Not all IDE RAID controllers are supported. If your RAID controller is not yet supported by dmraid, you may combine drives into RAID arrays by configuring Linux software RAID. For supported controllers, configure the RAID functions in the computer BIOS.
Multiple NICs and PXE Installation
Some servers with multiple network interfaces may not assign eth0 to the first network interface as BIOS knows it, which can cause the installer to try using a different network interface than was used by PXE. To change this behavior, use the following in pxelinux.cfg/* config files:
IPAPPEND 2 APPEND ksdevice=bootif
The configuration options above causes the installer to use the same network interface as BIOS and PXE use. You can also use the following option:
ksdevice=link
This option causes the installer to use the first network device it finds that is linked to a network switch.
Upgrade Related Issues
Refer to http://fedoraproject.org/wiki/DistributionUpgrades for detailed recommended procedures for upgrading Fedora.
Emacs
If you are upgrading to Fedora 9 and use emacs, you must upgrade to the latest version of emacs for your prior release to ensure a clean upgrade. Fedora 8 users must have emacs-22.1-10.fc8 or later.
SCSI driver partition limits
Whereas older IDE drivers supported up to 63 partitions per device, SCSI devices are limited to 15 partitions per device. Anaconda uses the libata driver in the same fashion as the rest of Fedora, so it is unable to detect more than 15 partitions on an IDE disk during the installation or upgrade process.
If you are upgrading a system with more than 15 partitions, you may need to migrate the disk to Logical Volume Management (LVM). This restriction may cause conflicts with other installed systems if they do not support LVM. Most modern Linux distributions support LVM and drivers are available for other operating systems as well.
Disk partitions must be labelled
A change in the way that the linux kernel handles storage devices means that device names like /dev/hdX or /dev/sdX may differ from the values used in earlier releases. Anaconda solves this problem by relying on partition labels or UUIDs for finding devices. If these are not present, then Anaconda presents a warning indicating that partitions need to be labelled and that the upgrade can not proceed. Systems that use Logical Volume Management (LVM) and the device mapper usually do not require relabeling.
To check disk partition labels
To view partition labels, boot the existing Fedora installation, and enter the following at a terminal prompt:
/sbin/blkid
Confirm that each volume line in the list has a LABEL= value, as shown below:
/dev/hdd1: LABEL="/boot" UUID="ec6a9d6c-6f05-487e-a8bd-a2594b854406" SEC_TYPE="ext2" TYPE="ext3"
To set disk partition labels
For ext2 and ext3 partitions without a label, use the following command:
su -c 'e2label /dev/example f7-slash'
For a VFAT filesystem use dosfslabel from the dosfstools package, and for NTFS filesystem use ntfslabel from the ntfsprogs package. Before rebooting the machine, also update the file system mount entries, and the GRUB kernel root entry.
Update the file system mount entries
If any filesystem labels were added or modified, then the device entries in /etc/fstab must be adjusted to match:
su -c 'cp /etc/fstab /etc/fstab.orig' su -c 'gedit /etc/fstab'
An example of a mount by label entry is:
LABEL=f7-slash / ext3 defaults 1 1
Update the grub.conf kernel root entry
If the label for the / (root) filesystem was modified, the kernel boot parameter in the grub configuration file must also be modified:
su -c 'gedit /boot/grub/grub.conf'
A matching example kernel grub line is:
kernel /vmlinuz-2.6.20-1.2948.fc6 ro root=LABEL=f7-slash rhgb quiet
Test changes made to labels
If partition labels were adjusted, or the /etc/fstab file modified, then boot the existing Fedora installation to confirm that all partitions still mount normally and login is successful. When complete, reboot with the installation media to start the installer and begin the upgrade.
Upgrades versus fresh installations
In general, fresh installations are recommended over upgrades, particularly for systems that include software from third-party repositories. Third-party packages remaining from a previous installation may not work as expected on an upgraded Fedora system. If you decide to perform an upgrade anyway, the following information may be helpful:
Before you upgrade, back up the system completely. In particular, preserve /etc, /home, and possibly /opt and /usr/local if customized packages are installed there. You may wish to use a multi-boot approach with a "clone" of the old installation on alternate partition(s) as a fallback. In that case, create alternate boot media, such as a GRUB boot floppy.
After you complete the upgrade, run the following command:
rpm -qa --last > RPMS_by_Install_Time.txt
Inspect the end of the output for packages that pre-date the upgrade. Remove or upgrade those packages from third-party repositories, or otherwise deal with them as necessary. Some previously installed packages may no longer be available in any configured repository. To list all these packages, use the following command:
su -c 'yum list extras'
Kickstart HTTP Issue
When using a Kickstart configuration file via HTTP, kickstart file retrieval may fail with an error that indicates the file could not be retrieved. Click the OK button several times without making modifications to override this error successfully. As a workaround, use one of the other supported methods to retrieve Kickstart configurations.
Architecture Specific Notes
This section provides notes that are specific to the supported hardware architectures of Fedora.
RPM multiarch support on 64-bit platforms (x86_64, ppc64)
RPM supports parallel installation of multiple architectures of the same package. A default package listing such as rpm -qa might appear to include duplicate packages, since the architecture is not displayed. Instead, use the repoquery command, part of the yum-utils package, which displays architecture by default. To install yum-utils, run the following command:
su -c 'yum install yum-utils'
To list all packages with their architecture using rpm, run the following command:
rpm -qa --queryformat "%{name}-%{version}-%{release}.%{arch}\n"
You can add this to /etc/rpm/macros (for a system wide setting) or ~/.rpmmacros (for a per-user setting). It changes the default query to list the architecture:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}

Fedora Live Images
The Fedora 10 release includes several Live ISO images in addition to the traditional installation images. These ISO images are bootable, and you can burn them to media and use them to try out Fedora. They also include a feature that allows you to install the Live image content to your hard drive for persistence and higher performance.
Available Images
For a complete list of current spins available, and instructions for using them, refer to:
http://fedoraproject.org/wiki/CustomSpins
Usage Information
To boot from the Live image, insert it into your computer and restart. To log in and use the desktop environment, enter the username fedora. There is no password on this account. The GNOME-based Live images automatically login after one minute, so users have time to select a preferred language. After logging in, if you wish to install the contents of the live image to your hard drive, click on the Install to Hard Drive icon on the desktop.
Text Mode Installation
You can do a text mode installation of the Live images using the liveinst command in the console.
USB Booting
Another way to use these Live images is to put them on a USB stick. To do this, you can use liveusb-creator graphical interface. You can use Add/Remove software, search and install liveusb-creator or install using yum:
yum install liveusb-creator
You can also use the command line interface, install the livecd-tools package from the repository. Then, run the livecd-iso-to-disk script:
/usr/bin/livecd-iso-to-disk /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
This is not a destructive process; any data you currently have on your USB stick is preserved.
Persistent Home Directory
Support for keeping a persistent /home with the rest of the system stateless has been added for Fedora 10. This includes support for encrypting /home to protect your system in the case where your USB stick is lost or stolen. To use this, download the live image and run the following command:
livecd-iso-to-disk --home-size-mb 512 /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
Replace 512 with the desired size in megabytes of the persistent /home. The livecd-iso-to-disk shell script is stored in the LiveOS directory at the top level of the CD image. The USB media must have sufficient free space for the Live image, plus the /home, plus any other data to be stored on the media. By default, this will encrypt your data and prompt for a passphrase to use. If you want to have an unencrypted /home, then you can specify --unencrypted-home
Note that later runs of livecd-iso-to-disk will preserve the /home that is created on the USB stick and it will continue to be used even if you change your live image.
Live USB Persistence
Support for persistent changes with a Live image exists for Fedora 9 and later. The primary use case is booting from a Live image on a USB flash drive and storing changes to that same device. To do this, download the Live image and then run the following command:
livecd-iso-to-disk --overlay-size-mb 512 /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
Replace 512 with the desired size in megabytes of the persistent data, or overlay. The livecd-iso-to-disk shell script is stored in the LiveOS directory at the top level of the CD image. The USB media must have sufficient free space for the Live image, plus the overlay, plus any other data to be stored on the media.
Booting a Live Image Off of USB on Intel-based Mac Hardware
Fedora 10 includes support for putting the live image onto a USB image and then booting it on Intel Mac hardware. Unlike for most x86 machines, this unfortunately requires reformatting the USB stick which you are using. To set up a stick for this, you can run
/usr/bin/livecd-iso-to-disk --mactel /path/to/live.iso /dev/sdb1
Replace /dev/sdb1 with the partition where you want to put the image.
Note that all of the other arguments for the livecd-iso-to-disk tool as described above can be used here as well.
Differences From a Regular Fedora Install
The following items are different from a normal Fedora install with the Live images.
- Live images provide a subset of packages available in the regular DVD image. Both connect to the same repository that has all the packages.
- SSH is disabled by default. SSH is disabled because the default username in the Live images does not have any password. However, installation to hard disk prompts for creating a new username and password.
- Live image installations do not allow any package selection or upgrade capability since they copy the entire file system from media or USB disks, to the hard disk. After the installation is complete, and your system has been rebooted, you can add and remove packages as desired with the Add/Remove Packages tool,
yum, or the other software management tools. - Live images do not work on
i586architecture.
Package Notes
The following sections contain information regarding software packages that have undergone significant changes for Fedora 10. For easier access, they are generally organized using the same groups that are shown in the installation system.
Sound Card Utility
The system-config-soundcard utility has been removed, due to numerous legacy design and implementation issues. Modern technologies, including udev and the HAL, have made most sound cards work out of the box. Any sound card not working out of the box should be reported as a bug . Preferences can still be fine-tuned within the desktop environment, using, among others, the PulseAudio tools.
Perl
Fedora 9 now includes Perl 5.10.0, the first "major" release update in perl5 in some time. The Perl interpreter itself is faster with a smaller memory footprint, and has several UTF-8 and threading improvements. The Perl installation is now relocatable, a blessing for systems administrators and operating system packagers. Perl 5.10.0 also adds a new smart match operator, a switch statement, named captures, state variables, and better error messages.
For more information, refer to:
http://perldoc.perl.org/perldelta.html
Yum Changes
The installonlyn plugin functionality has been folded into the core yum package. The installonlypkgs and installonly_limit options are used by default to limit the system to retain only two kernel packages. You can adjust the package set or the number of packages, or disable the option entirely to match your preferences. More details is available in the man page for yum.conf.
The yum command now retries when it detects a lock. This function is useful if a daemon is checking for updates, or if you are running yum and one of its graphical frontends simultaneously.
The yum command now understands a cost parameter in its configuration file, which is the relative cost of accessing a software repository. It is useful for weighing one software repository's packages as greater or less than any other. The cost parameter defaults to 1000, with lower costs given priority.
In Fedora 9 Rawhide, the /etc/yum.repos.d/fedora-development.repo file has been changed to /etc/yum.repos.d/fedora-rawhide.repo. References to development in fedora-rawhide.repo have been changed to rawhide. Due to the way that RPM deals with configuration files, the existing /etc/yum.repos.d/fedora-development.repo file is saved as /etc/yum.repos.d/fedora-development.repo.rpmsave if it was previously modified. Users of the development repository may need to update scripts and custom configuration files to use the new name.
pam_mount
The pam_mount facility now uses a configuration file written in XML. The /etc/security/pam_mount.conf file will be converted to /etc/security/pam_mount.conf.xml during update with /usr/bin/convert_pam_mount_conf.pl, which removes all comments. Any per-user configuration files must be converted manually, with the conversion script if desired. A sample pam_mount.conf.xml file with detailed comments about the available options appears at /usr/share/doc/pam_mount-*/pam_mount.conf.xml.
TeXLive
TeXLive is a replacement for the old, unmaintained TeX package. It offers new style packages and fixes many security problems with the old distribution.
LTSP
The Linux Terminal Server Project (LTSP) has been included directly into Fedora 9. Work is ongoing. For the latest news and documentation, refer to:
http://k12linux.fedorahosted.org/
Utility Packages
The nautilus-open-terminal package now uses a GConf key to control its behavior when launched by right-clicking the Desktop. To enable its previous behavior, which opens the resulting terminal in the user's home directory, use this command:
gconftool-2 -s /apps/nautilus-open-terminal/desktop_opens_home_dir --type=bool true
The i810switch package has been removed. This functionality is now available through the xrandr command in the xorg-x11-server-utils package.
The evolution-exchange package replaces evolution-connector, and provides a capability under the old name.
The system-config-firewall and system-config-selinux packages replace system-config-security-level. The system-config-selinux package is part of the the policycoreutils-gui package.
pilot-link and HAL/PolicyKit Interaction
The pilot-link package now blacklists the visor module by default. Users are encouraged to try the direct USB access present in recent versions of pilot-link. This is enabled by passing the --port usb: option to the various pilot-link tools, instead of the serial devices used in the past (typically /dev/pilot or /dev/ttyUSB0, /dev/ttyUSB1, and so forth). For example:
pilot-xfer --port usb: --list
The hal-info and hal packages have been updated to correctly set permissions for the necessary USB devices using PolicyKit. If you have any existing manual configurations, revert the changes to avoid possible conflicts.
For further information, refer to the README.fedora included in the pilot-link package.
GIMP
Fedora 10 includes version 2.6 of the GNU Image Manipulation Program.
This new version is designed to be backwards compatible, so existing third party plug-ins and scripts should continue to work -- with a minor caveat: The included Script-Fu Scheme interpreter doesn't accept variable definitions without an initial value anymore (which isn't compliant to the language standard). Scripts included in Fedora packages should not have this problem, but if you use scripts from other sources, please refer to the GIMP Release notes for more details and how you can fix scripts that have this problem.
Additionally, the gimptool script which is used to build and install third party plug-ins and scripts has been moved from the gimp to the gimp-devel package. Install this package if you want to use gimptool.

Linux Kernel
This section covers changes and important information regarding the 2.6.27 based kernel in Fedora 10. The 2.6.27 kernel includes:
- Tickless support for x86 64bit systems (32 bit was added previously), which greatly improves power management.
- Some elements of the realtime kernel project.
- The kernel has a new version naming scheme to more closely match the upstream version naming scheme.
- The kernel spec file is now named
kernel.specrather thankernel-2.6.spec. - The kernel spec file has new macros that ease the kernel building process. Refer to http://fedoraproject.org/wiki/Docs/CustomKernel for further information.
- The kernel in Fedora 10 no longer loads modules by default for ISA sound cards. Load the module by hand using the command
modprobe module-name, or put an entry in/etc/modprobe.conf. For example, for the Creative SoundBlaster AWE64, add the following entry:
install snd-sbawe
- The Fedora kernel offers
paravirt_opssupport indomU, as part of the kernel team's efforts to reduce the work required to produce current Xen kernels. - Xen fully virtualized guests can directly boot a kernel and
initrdimage and pass kernel boot args. For more details refer to http://fedoraproject.org/wiki/Features/XenFullvirtKernelBoot.
Version
Fedora may include additional patches to the kernel for improvements, bug fixes, or additional features. For this reason, the Fedora kernel may not be line-for-line equivalent to the so-called vanilla kernel from the kernel.org web site:
To obtain a list of these patches, download the source RPM package and run the following command against it:
rpm -qpl kernel-<version>.src.rpm
Changelog
To retrieve a log of changes to the package, run the following command:
rpm -q --changelog kernel-<version>
If you need a user friendly version of the changelog, refer to http://wiki.kernelnewbies.org/LinuxChanges. A short and full diff of the kernel is available from http://kernel.org/git. The Fedora version kernel is based on the Linus tree.
Customizations made for the Fedora version are available from http://cvs.fedoraproject.org.
Kernel Flavors
Fedora 10 includes the following kernel builds:
- Native kernel, for use in most systems. Configured sources are available in the
kernel-develpackage.
- The kernel-PAE, for use in 32-bit x86 systems with more than 4GB of RAM, or with CPUs that have a NX (No eXecute) feature. This kernel support both uniprocessor and multi-processor systems. Configured sources are available in the
kernel-PAE-develpackage.
- Virtualization kernel for use with the Xen emulator package. Configured sources are available in the
kernel-xen-develpackage.
You may install kernel headers for all four kernel flavors at the same time. The files are installed in the /usr/src/kernels/<version>[-PAE|-xen|-kdump] -<arch>/ tree. Use the following command:
su -c 'yum install kernel{,-PAE,-xen,-kdump}-devel'
Select one or more of these flavors, separated by commas and no spaces, as appropriate. Enter the root password when prompted.
Preparing for Kernel Development
Fedora 10 does not include the kernel-source package provided by older versions since only the kernel-devel package is required now to build external modules. Configured sources are available, as described [#Kernel_Flavors above].
Reporting Bugs
Refer to http://kernel.org/pub/linux/docs/lkml/reporting-bugs.html for information on reporting bugs in the Linux kernel. You may also use http://bugzilla.redhat.com for reporting bugs that are specific to Fedora.
Fedora Desktop
This section details changes that affect Fedora graphical desktop users.
Better Webcam support
Fedora 10 comes with much improved support for webcams.
Next to improvements to the UVC driver which was first introduced in Fedora 9 and supports any webcam with a vista compliant logo, Fedora 10 also features a brand new v4l2 version of gspca, an usb webcam driver framework with support for many different usb webcam bridges and sensors.
Userspace support for webcams has also been improved by adding libv4l and updating all webcam using applications to use libv4l, this makes these applications understand the often manufacturer specific and custom video formats emitted by many webcams, esp. by many of the webcams supported by gspca.
For a list of all webcams and applications with which Fedora-10's new webcam support has been tested see the BetterWebcamSupport feature page, for a list of all cams supported by the original version of gspca see the original gspca website. The v4l2 version of gspca in Fedora-10 supports all these webcams and more.
Plymouth Graphical Boot
The graphical boot up system used in previous Fedora versions called rhgb is being replaced with a new system called Plymouth. There are a few issues with Plymouth in the Beta:
- Adding
rhgbon the command line directs Plymouth to load the appropriate plugin for your hardware.
- The graphical boot splash screen that comes with Plymouth requires kernel mode setting drivers to work best. There are not kernel modesetting drivers available for all hardware yet. To see the graphical splash before the drivers land, add
vga=0x318to the kernel grub command line. This usesvesafb, which does not necessarily give the native resolution for the flat panel, and may cause flickering or other weird interactions with X. Without kernel modesetting drivers orvga=0x318, Plymouth uses a text-based plugin that is plain but functional.
- Currently, only Radeon R500 and higher users will get kernel modesetting by default. There is work in progress to provide modesetting for R100 and R200. Additionally, Intel kernel modesetting drivers are in development, but not turned on by default.
- The kernel modesetting drivers are still in active development. If you end up with nothing but a black screen during boot up, or a screen with nothing but random noise on it, then adding "nomodeset" to the kernel boot prompt in
grubdisables modesetting.
- Plymouth hides boot messages. To view boot messages, press the [Esc] key during boot, or view them in
/var/log/boot.logafter boot up. Alternatively, removerhgbfrom the kernel command line and plymouth will display all boot messages. There is also a status icon on the login screen to view boot warnings.
Echo Icon Theme
Echo is an icon theme developed for Fedora by the volunteer art community. It inherits the isometric perspective from the classic Bluecurve theme while introducing a refreshing new look. It follows the freedesktop.org theme specification. Current version covers essential icons from the desktop menus and applications. Future revisions will bring more broader coverage.
Currently, both GNOME and Xfce uses the Echo icon theme by default. KDE continues to use the Oxygen icon theme. The next release of Fedora will potentially introduce Echo by default for KDE as well for a consistent look and feel across different desktop environments.
GNOME
This release features GNOME 2.24.
Empathy Instant Messenger
Empathy instant messenger is the new default replacing Pidgin in this release. It has support for multiple protocols including IRC, XMPP(Jabber), Yahoo, MSN and others via plugins. It also supports video and voice in the XMPP protocol and support for other protocols is under active development. Empathy uses the telepathy framework that has a number of additional plugins:
- telepathy-gabble - Jabber/XMPP lugin
- telepathy-idle - IRC plugin
- telepathy-butterfly - MSN plugin
- telepathy-sofiasip - SIP plugin
- telepathy-haze - Libpurple(Pidgin) library connection manager provides support for other protocols such as Yahoo
Pidgin continues to be available in the Fedora software repository and will be retained as the default for users upgrading from previous releases of Fedora.
GNOME Display Manager
The GNOME Display Manager (gdm) has been updated to the latest upstream code, which is a complete rewrite driven by Fedora developers. PolicyKit can be used to control shutdown and reboot. The configuration tool gdmsetup is missing currently, and set to be replaced. For configuration changes, refer
http://live.gnome.org/GDM/2.22/Configuration
KDE
This release features KDE 4.1.2. As the kdevelop packages is not part of KDE 4.1 and kdewebdev is only partially available (no Quanta) in KDE 4.1, the KDE 3.5.10 versions of those packages are shipped. A kdegames3 package containing the games not yet ported to KDE 4 is also available.
KDE 4.1 is the latest feature release of KDE 4. It features several new features and many usability improvements and bugfixes over KDE 4.0, the first KDE 4 release series, including a folder view desktop applet (plasmoid), improvements to Dolphin and Konqueror and many new and improved applications. KDE 4.1.2 is a bugfix release from the KDE 4.1 release series.
Fedora 10 does not include the legacy KDE 3 Desktop. It does include a compatibility KDE 3 Development Platform, which can be used to build and run KDE 3 applications within KDE 4 or any other desktop environment. Refer to the Backwards Compatibility section for more details about what is included.
Fedora 10 includes a snapshot of knetworkmanager which works with the prerelease of NetworkManager 0.7 in Fedora 10. As it was not considered ready for production use, the KDE Live images use nm-applet from NetworkManager-gnome instead (as in Fedora 8 and 9). The gnome-keyring-daemon facility saves passwords for these encryption technologies. knetworkmanager can, however, be installed from the repository.
As the native KWin window manager now optionally supports compositing and desktop effects, the KDE Live images no longer include Compiz/Beryl (since Fedora 9). The KWin compositing/effects mode is disabled by default, but can be enabled in systemsettings. Compiz (with KDE 4 integration) is available from the repository by installing the compiz-kde package.
Enhancements
- Plasma is more mature and panel configuration has been extended. The new panel controller makes it easy to customize your panel providing direct visual feedback. The Plasma's Folderview applet provides a view of a directory and thus allows you to store files on desktop. It is replacement for well known icons on desktop.
Package and Application Changes
- Fedora 10 ships
kdepim4.1.2 instead of 3.5.x. -
libkipi,libkexiv2andlibkdcrawhave been obsoleted by the KDE 4 versions in thekdegraphicspackage. Accordingly,kipi-plugins,digikamandkphotoalbumhave been updated to KDE 4 versions. -
kpackagekit, a KDE frontend to PackageKit, is now available. (It may be made available as an update for Fedora 9 at a later time.)
In addition, the following changes made since the Fedora 9 release, which have been backported to Fedora 9 updates, are also part of Fedora 10:
- KDE has been upgraded from version 4.0.3 to 4.1.2.
-
qtandPyQt4have been upgraded from 4.3 to 4.4. -
kdewebdev,kdevelop,kdegames3and the KDE 3 backwards-compatibility libraries have been upgraded from KDE 3.5.9 to 3.5.10. - QtWebKit is now part of the
qtpackage. The standaloneWebKit-qtpackage has been obsoleted. - The new package
qgtkstylecontains a Qt 4 style using GTK+ for drawing, providing better integration of Qt 4 and KDE 4 applications into GNOME. -
phonon, which was part ofkdelibsin Fedora 9, is now a separate package. An optional GStreamer backend (phonon-backend-gstreamer) is now available, but the xine-lib backend, which is now packaged asphonon-backend-xine, is still the recommended default backend and is now required by thephononpackage. - The
kdegames3package no longer provides development support for the KDE 3 version of libkdegames because nothing in Fedora outside ofkdegames3itself requires that library anymore. - The package
oktetais now part ofkdeutils. - The package
dragonplayeris now part ofkdemultimedia. -
kaiderhas been renamed to Lokalize and is now part ofkdesdk. - The package
ksirkhas been ported to KDE 4 and is now part ofkdegames. - The package
extragear-plasmahas been renamed tokdeplasma-addons.
Web Browsers
Enabling Flash Plugin
Fedora includes swfdec and gnash, which are free and open source implementations of Flash. We encourage you to try either of them before seeking out Adobe's proprietary Flash Player plug-in software. The Adobe Flash Player plug-in uses a legacy sound framework that does not work correctly without additional support. Run the following command to enable this support:
su -c "yum install libflashsupport"
If you are using Flash 10, you do not need libflashsupport anymore as the usage of ALSA has been fixed in this version.
Users of Fedora x86_64 must install the nspluginwrapper.i386 package to enable the 32-bit Adobe Flash Player plug-in in Firefox, and the libflashsupport.i386 package to enable sound from the plug-in.
- Install the
nspluginwrapper.i386,nspluginwrapper.x86_64, andlibflashsupport.i386packages:
su -c "yum install nspluginwrapper.{i386,x86_64} libflashsupport.i386"
- Install
flash-pluginas shown above after nspluginwrapper.i386 is installed.
- Run
mozilla-plugin-configto register the flash plugin:
su -c "mozilla-plugin-config -i -g -v"
- Close all Firefox windows, and then relaunch Firefox.
- Type
about:pluginsin the URL bar to ensure the plugin is loaded.
Disabling PC Speaker
PC speaker is enabled by default in Fedora. If you do not prefer this, there are two ways to circumvent the sounds:
- Reduce its volume to a acceptable level or completely mute the PC speaker in
alsamixerwith the setting for PC Speak.
- Disable the PC speaker system wide by running the following commands in a console.
su - modprobe -r pcspkr echo "install pcspkr :" >> /etc/modprobe.conf

File Systems
eCryptfs
While Fedora 9 debuted encrypted fileystem support, F10 builds on that and fixes a number of problems that could have resulted in data corruption.
EXT4
Fedora 9 debuted a preview of ext4 support. F10 brings a fully ext4-compatible e2fsprogs. In addition Anaconda's partition screen has an ext4 filesystem option available if you launch the installer with the ext4 option. Fedora 10 also brings delayed allocation for ext4. However, ext4 in Fedora 10 doesn't currently support filesystems larger than 16 terabytes.
XFS
XFS is now a supported filesystem and an option with the the partitioning screen of Anaconda
File Servers
This section refers to file transfer and sharing servers. Refer to http://fedoraproject.org/wiki/Docs/Beats/WebServers and http://fedoraproject.org/wiki/Docs/Beats/Samba for information on HTTP (Web) file transfer and Samba (Windows) file sharing services.

Web Servers
PostgreSQL DBD Driver
Users of the mod_dbd module should note that the apr-util DBD driver for PostgreSQL is now
distributed as a separate dynamically-loaded module. The driver module is now included in the
apr-util-pgsql package. A MySQL driver is now also available, in the apr-util-mysql package.
TurboGears Applications
The main !CherryPy package has been updated to 3.x. A compatibility package for !TurboGears applications has been created: python-cherrypy2. !TurboGears applications created before this change may need to update their startup scripts. Instead of:
import pkg_resources
pkg_resources.require('TurboGears')
the start script needs to have:
__requires__ = 'TurboGears' import pkg_resources
Drupal
Drupal has been updated to 6.4. For details, refer to:
If you're already updated to the latest in F-9, which is also 6.4, you don't need to do the following:
Remember to log in to your site as the admin user, and disable any third-party modules before upgrading this package. After upgrading the package:
1. Copy /etc/drupal/default/settings.php.rpmsave to /etc/drupal/default/settings.php, and repeat for any additional sites' settings.php files.
1. Browse to http://host/drupal/update.php to run the upgrade script.
Also, several modules are now available. drupal-date, -cck, -views, and -service_links.
Squid
Squid has been updated from version 2.6 to 3.0.STABLE2. The configuration files are not entirely backwards compatible. For further details, refer to the Squid release notes:
http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE2-RELEASENOTES.html
As well, due to a bug, the transparent proxy does not work. This should be resolved after the first update.
Mail Servers
This section concerns electronic mail servers or mail transfer agents (MTAs).
Sendmail
By default, the Sendmail mail transport agent (MTA) does not accept network connections from any host other than the local computer. To configure Sendmail as a server for other clients:
1. Edit /etc/mail/sendmail.mc and either change the DAEMON_OPTIONS line to also listen on network devices, or comment out this option entirely using the dnl comment delimiter.
1. Install the sendmail-cf package:
yum install sendmail-cf
1. Regenerate /etc/mail/sendmail.cf:
make -C /etc/mail

Security
This section highlights various security items from Fedora.
Security Enhancements
Fedora continues to improve its many proactive security features .
Support for SHA-256 and SHA-512 passwords
The glibc package in Fedora 8 had support for passwords using SHA-256 and SHA-512 hashing. Previously, only DES and MD5 were available. These tools have been extended in Fedora 9. Password hashing using the SHA-256 and SHA-512 hash functions is now supported.
To switch to SHA-256 or SHA-512 on an installed system, use authconfig --passalgo=sha256 --update or authconfig --passalgo=sha512 --update. Alternatively, use the authconfig-gtk GUI tool to configure the hashing method. Existing user accounts will not be affected until their passwords are changed.
SHA-512 is used by default on newly installed systems. Other algorithms can be configured only for kickstart installations, by using the --passalgo or --enablemd5 options for the kickstart auth command. If your installation does not use kickstart, use authconfig as described above, and then change the root user password, and passwords for other users created after installation.
New options now appear in libuser, pam, and shadow-utils to support these password hashing algorithms. Running authconfig configures all these options automatically, so it is not necessary to modify them manually.
- New values for the
crypt_styleoption, and the new optionshash_rounds_min, andhash_rounds_max, are now supported in the[defaults]section of/etc/libuser.conf. Refer to thelibuser.conf(5)man page for details.
- New options,
sha256,sha512, androunds, are now supported by thepam_unixPAM module. Refer to thepam_unix(8)man page for details.
- New options,
ENCRYPT_METHOD,SHA_CRYPT_MIN_ROUNDS, andSHA_CRYPT_MAX_ROUNDS, are now supported in/etc/login.defs. Refer to thelogin.defs(5)man page for details. Corresponding options were added tochpasswd(8)andnewusers(8).
FORTIFY_SOURCE extended to cover more functions
FORTIFY_SOURCE protection now covers asprintf, dprintf, vasprintf, vdprintf, obstack_printf and obstack_vprintf. This improvement is particularly useful for applications that use the glib2 library, as several of its functions use vasprintf.
SELinux Enhancements
Different roles are now available, to allow finer-grained access control:
-
guest_tdoes not allow running setuid binaries, making network connections, or using a GUI. -
xguest_tdisallows network access except for HTTP via a Web browser, and no setuid binaries. -
user_tis ideal for office users: prevents becoming root via setuid applications. -
staff_tis same asuser_t, except that root access viasudois allowed. -
unconfined_tprovides full access, the same as when not using SELinux.
As well, browser plug-ins wrapped with nspluginwrapper, which is the default, now run confined.
Default Firewall Behavior
In Fedora 9, the default firewall behavior has changed. There are no default ports open, except for SSH (22), which is opened by Anaconda.

OpenJDK
OpenJDK 6
Fedora 9 includes OpenJDK 6, a Free Software implementation of the Java Platform, Standard Edition. OpenJDK 6 is not yet Java compatible; work is underway to certify it.
Fedora will track Sun's stable OpenJDK 6 branch.
OpenJDK Replaces IcedTea
The OpenJDK 6 packages, java-1.6.0-openjdk*, replace their IcedTea counterparts, java-1.7.0-icedtea*. The Fedora 8 IcedTea packages track the unstable OpenJDK 7 branch, whereas the java-1.6.0-openjdk* packages track the stable OpenJDK 6 branch. The decision to have OpenJDK 6 replace IcedTea was made for several reasons:
- Sun has replaced most of the encumbrances for which IcedTea was providing replacements. For the rest of the encumbrances, replacements have been merged from the IcedTea project.
- IcedTea's mandate is to merge as much as possible with OpenJDK, so the differences between IcedTea and OpenJDK should diminish over time.
- OpenJDK 6 is a stable branch, whereas OpenJDK 7 is unstable, and is not expected to ship a stable release until 2009.
- Sun has licensed the OpenJDK trademark for use in Fedora.
- Shipping both OpenJDK 6 and IcedTea would have been confusing, and would have added size to the distribution.
IcedTea continues to provide autotools support (autoconf, automake, libtool, and so on), a portable interpreter for PowerPC and 64-bit PowerPC architectures, plugin support, Web Start support, and patches to integrate OpenJDK into Fedora. The IcedTea sources are included in the java-1.6.0-openjdk SRPM.
If IcedTea is already installed, the package changeover does not happen automatically. The packages related to IcedTea based on OpenJDK 7 must first be erased, then the new OpenJDK 6 packages installed.
su -c "yum erase java-1.7.0-icedtea{,-plugin}"
su -c "yum install java-1.6.0-openjdk{,-plugin}"
Handling Java Applets
Upstream OpenJDK does not provide a plugin. The Fedora OpenJDK packages include an adaptation of gcjwebplugin, that runs untrusted applets safely in a Web browser. The plugin is packaged as java-1.6.0-openjdk-plugin.
