Virtualbox tip

Users of Fedora/Mandriva might want to install the dkms package (not available on openSUSE) to ensure that the VirtualBox host kernel modules (vboxdrv, vboxnetflt and vboxnetadp) are properly updated if the linux kernel version changes during the next kernel update.

 

# yum install dkms

Fedora 11: Leonidas (Release notes Overview)

Today (June 09, 2009) F11: Leonidas released

download link:  http://fedoraproject.org/en/get-fedora

torrent: http://torrent.fedoraproject.org

upgrade from F10: # preupgrade

.

1. Presto (yum-delta): activating via install yum-presto

• Presto – When you update a package,  Presto allows you to download the difference (called the delta) between the package. This can reduce the download size of updates by 60% – 80%. It is not enabled by default for this release. To make use of this feature you must install the yum-presto plugin with yum install yum-presto.
• further details refer to the Presto wiki page

2. EXT4 as a default filesystem

• Ext4 filesystem – The ext4 file system is a major update that has an improved design, even better performance and reliability, support for much larger storage, and very fast file system checks and file deletions. It is now the default filesystem for new installations.

3. IBUS input method system

• IBus input method system – ibus has been rewritten in C and is the new default input method for Asian languages. It allows input methods to be added and removed dynamically during a desktop session. It supports Chinese (pinyin, libchewing, tables), Indic (m17n), Japanese (anthy), Korean (libhangul), and more. There are still some features missing compared to scim so testing is strongly encouraged and reports of problems and suggestions for improvements welcome.

4. improved Virt Console

• Virt Improved Console – In Fedora 11 the goal is to have the screen default to at least 1024×768 resolution(800×600 for Fedora 10) out of the box. New installations of F11 provide the ability to use other interface devices in the virtual guest, such as a USB tablet, which the guest will automatically detect and configure. Among the results is a mouse pointer that tracks the local client pointer one-for-one, and providing expanded capabilities.

5. MinGW (Windows cross compiler)

6. Intel, ATI and Nvidia kernel modsetting

7. Automatic font and mime-type installation

8. Volume Control

9. Fingerprint

.

Features for Fedora 11 tracked on the feature list page:
