Youcan deploy it on a wide range of thick client devices (includingdesktops, notebooks, netbooks, and workstations), on thin clientdevices, or as a virtual desktop. By leveraging the power of SUSE Linux Enterprise  Desktop,your business can dramatically reduce costs, improve end-usersecurity and increase workforce productivity.  


New Features
5.1 Desktop
  •      GNOME 2.28    

         GNOME was updated to version 2.28 with SP1, only selected       packages got an update for SP2 or SP3.    

  •      KDE 4.3    

         SUSE introduced KDE 4 with SUSE Linux Enterprise Desktop 11 as an      innovative free software desktop and applications such as the      Konqueror web browser, the Dolphin file manager, the Okular      document reader, the System Settings control center and more.    

         KDE was updated to 4.3.4 version with SP1.    

         This new version of KDE is built on KDE Libraries which provide      easy access to resources on the network by means of KIO and      advanced visual capabilities through Qt4.  Phonon and      Solid. Customers migrating from SUSE Linux Enterprise  Desktop 10 using KDE are getting a      new user experience in version 11 Service Pack 1 and later. We recommend      backing up your user home directory when upgrading from      SUSE Linux Enterprise  Desktop 10. (Partly based on http://www.kde.org/announcements/4.0/.)    

  •      X.org 7.4    

         The X server libraries were updated to version 1.6.5. The client      libraries were kept the same, except for libgl.    

5.1.1 fbdev Driver Needs Reboot After Resolution Changes

SaX2 offers to change the resolution even for the fbdev driver.Because this is controlled via a VGA kernel option, rebooting isneeded after resolution changes.  In other words: Modificationswill take effect the next time the graphics system is restarted;in some cases a reboot of the machine is needed.

5.1.2 LibreOffice Replaces OpenOffice.org

   Since SUSE Linux Enterprise Desktop 11 SP1, Openoffice.org has been    replaced with LibreOffice.  If you perform an upgrade, manual    interaction is needed, otherwise you will stay with the old    OpenOffice.org packages.  Future updates will only be prepared and    published for LibreOffice.  

   Some parts of the documentation packages still mention    'OpenOffice.org'.  

5.2 Security
5.2.1 Switch repomd from sha to sha26

The update repository integrity used by SUSE is ensured by a GPG signature and the checksums of the YUM repomd XML metadata.

SUSE Linux Enterprise 11 so far used sha1 as intermediate checksum, which should no longer be used.

With SUSE Linux Enterprise 12 and SUSE Linux Enterprise 11 SP4 we start to use sha256 for the XML integrity handling and so get rid of the old sha1 hashing methods.

If you have tools parsing the XML metadata yourself, please verify they can handle also the newer sha256 hashes.

5.2.2 PAM Configuration

    The common PAM configuration files     (/etc/pam.d/common-*) are now created and     managed with pam-config.    

5.3 Server
5.3.1 numactl and libnuma

numactl and libnuma have been updated to the latest version.

This update comes with many bug fixes and some new features that are especially important for large NUMA systems, e.g.:

  • IO affinity support

  • New option to memhog to disable transparent huge pages

  • Show distances on machines without a node 0

5.4 Systems Management
  •      Improved Update Stack    

         SUSE Linux Enterprise  Desktop 11 comes with an improved update stack and the command      line tool zypper to manage the install/update      packages and repositories.    

  •      Enhanced YaST Partitioner    

  •      Extended Built-in Management Infrastructure    

         CIM enablement with SFCB CIMON.    

5.5 Kernel and Toolchain
  • GCC 4.3.4      

  • glibc 2.11      

  • Linux kernel 3.0      

5.6 Other Changes and Version Updates
  •       EVMS2 Replaced with LVM2      

  •       Default Filesystem      

          The default file system in new installations was changed from       ReiserFS to ext3 with SUSE Linux Enterprise  Desktop 11. A public statement can be found       at http://www.suse.com/products/server/technical-information/#FileSystem.      

  • Samba 3.4.3      

  • UEFI Enablement on AMD64      

  • SWAP over NFS      

  • Python 2.6.0      

  • Perl 5.10      

  • Ruby 1.87      

5.6.1 /etc/os-release

In addition to the /etc/SuSE-release file the file /etc/os-release is now available.

/etc/os-release is a cross-distribution standard to identify a Linux system. For more information about the syntax, see the os-release man page  ( man os-release ).


6.1 General Update Notes
6.1.1 Lower Version Numbers in SUSE Linux Enterprise 11 SP4 Than in Version 11 SP3

When upgrading from SUSE Linux Enterprise Server or Desktop 11 SP3 to version 11 SP4, you may encounter a version downgrade of specific software packages, including the Linux Kernel.

SLE 11 SP4 has all its software packages and updates in the SLE 11 SP4 repositories. No packages from SLE 11 SP3 repositories are needed for installation or upgrade, not even from the SLE 11 SP3 update repositories.

Note

It is important to remember that the version number is not sufficient to determine which bugfixes are applied to a software package.

In case you add SLE 11 SP3 update repositories, be aware of one characteristic of the repository concept: Version numbers in the SP3 update repository can be higher than those in the SP4 repository. Thus, if you update with the SP3 repositories enabled, you may get the SP3 version of a package instead of the SP4 version. This is admittedly unfortunate.

It is recommended to avoid using the version from a lower product or SP, because using the SLE 11 SP3 package instead of the SP4 package can result in unexpected side effects. Thus we advise to switch off all the SLE 11 SP3 repositories, if you do not really need them. Keep old repositories only, if your system depends on a specific older package version. If you need a package from a lower product or SP though, and thus have SLE 11 SP3 repositories enabled, make sure that the packages you intended to upgrade have actually been upgraded.

Summarizing: If you have an SLE 11 SP3 installation with all patches and updates applied, and then migrate off-line to SLE 11 SP4, you will see a downgrade of some packages. This is expected behavior.

6.1.2 Migrating to SLE 11 SP4 Using Zypper

  To migrate the system to the Service Pack 4 level with   zypper, proceed as follows:  

  •    Open a root shell.    

  •    To refresh all services and    repositories, run:    

    zypper ref -s
  •        To install package    management updates, run:    

    zypper patch
  •    Now it is possible to install all available updates for SLES/SLED 11    SP3; run again:    

    zypper patch
  •    Now the installed products contain information about distribution    upgrades and which migration products should be installed to perform    the migration. Read the migration product information from    /etc/products.d/*.prod and install them.    

  • Enter the following command:    

    grep '<product' /etc/products.d/*.prod

       A sample output could be as follows:    

    <product>sle-sdk-SP4-migration</product> <product>SUSE_SLED-SP4-migration</product>
  •    Install these migration products (example):    

    zypper in -t product sle-sdk-SP4-migration SUSE_SLED-SP4-migration
  • Run suse_register -d 2 -L /root/.suse_register.log toregister the products in order to get the corresponding SP4 Updaterepositories.    

  •         To avoid a dependency conflict enable the SLED11-Extras         repository with:        

    zypper mr -e SLED11-Extras

    On SLES this extra step is not needed.

  •    Run zypper ref -s to refresh services and repositores.    

  •    Check the repositories using zypper lr. Disable    SP1, SP2, and SP3 repositories after the registration and enable the new SP4    repositories (such as SP4-Pool, SP4-Updates):    

    zypper mr --disable <repo-alias> zypper mr --enable <repo-alias>

        Also disable repositories you do not want to update from.    

  •    Then perform a distribution upgrade by entering the following command:    

    zypper dup --from SLES11-SP4-Pool --from SLES11-SP4-Updates --from SLE11-SP2-WebYaST-1.3-Pool --from SLE11-SP2-WebYaST-1.3-Updates

        Add more SP4 repositories here if needed, e.g. in case add-on     products are installed.  For WebYaST, it is actually     SLE11-SP2-*, because there is one WebYaST     release that runs on two SP code bases.    

    NoteNote

         If you make sure that only repositories, which you migrate from, are      enabled, you can omit the --from parameters.    

  •    zypper will report that it will delete the migration product and update the main products. Confirm the message to continue updating the RPM packages.    

  •    To do a full update, run zypper patch.    

  •    After the upgrade is finished, register the new products again:    

    suse_register -d 2 -L /root/.suse_register.log
  •    Run zypper patch after re-registering.  Some     products do not use the update repositories during the migration and     they are not active at this point of time.    

  •     Reboot the system.
