openSUSE 11.2 Uitgavenotities

Configuring Boot Loader Location and Options

When setting the Boot Loader Location in the installation proposal, also set the Boot Loader Options. In the options adjust updates of the other system areas of your disk, which may influence the ability of openSUSE and the other installed systems to boot.

If the proposed boot loader configuration reports a warning, carefully review the boot loader configuration to avoid breaking the booting of other installed systems to ensure that openSUSE will boot.

openSUSE documentatie

• The new Installation QuickStart guides you step-by-step through the installation process.

• In the Start-Up Manual, find information about installation and basic system configuration.

• The Reference Guide covers deployment, administration, and system configuration in detail and explains how to set up variuos network services.

• The KDE and GNOME Quickstart guides give a short introduction to the desktops and some key applications running on it.

• The KDE and GNOME User Guides guide you through using and configuring the desktops and help you perform key tasks.

• The Application Guide introduces you to the key desktop applications such as browsers. e-mail clients, office applications and collaboration tools as well as graphics and multimedia applications.

• The Security Guide introduces basic concepts of system security, covering both local and network security aspects.

openSUSE documentatie als E-Boek (EPUB)

Naast de traditionele uitvoeropmaak PDF en HTML, is de openSUSE systeemdocumentatie nu beschikbbbbaar als e-boek in de EPUB-opmaak. EPUB (elektronische publicatie) is een vrije en open e-boekstandaard. Voor meer informatie over EPUB, zie http://en.wikipedia.org/wiki/EPUB.

De EPUB-bestanden downloaden van http://en.opensuse.org/Documentation.

YaST and X.Org Configuration (Keyboard, Mouse, Graphics Board, and Monitor)

In the past, YaST offered an configuration interface for the graphical desktop (X.org) such as keyboard, mouse, graphics board, and monitor. During the installation a suitable xorg.conf was created.

In most cases it is no longer needed because the Xserver is now able to automatically configure the system. If it fails for your system, try the following steps:

1. Check whether an old /etc/X11/xorg.conf file exists. If so, move it away and start your desktop again.

2. If it still does not work, run sax2 from the command line and execute the configuration procedure.

3. To adjust hardware components to your personal needs, start the GNOME desktop control center or Configure Desktop in KDE, and configure your devices such as the mouse or keyboard. The display configuration dialogs also let you configure multiple monitor setups. To configure multiple monitors, in other desktop environments, use xrandr.

For more information, see the Desktop User Guides shipping with openSUSE. They are also available from http://en.opensuse.org/Documentation

KDE

• Default Web Browser

  Firefox with special settings is now the KDE default browser in openSUSE. Users who want to prefer Konqueror as the KDE default browser can configure KDE accordingly (applications menu > 'Configure desktop'). There in the 'Default Applications' configuration module, select 'Web Browser' and change the radio button back to 'in an application based on the contents of the URL'. Desktop and panel Firefox icons can be replaced by deleting the Firefox icons and dragging the Konqueror icon from the applications menu to their place.

• KDE3

  KDE3 is no longer officially shipped with openSUSE. KDE4 is now the only supported KDE version. For information about KDE3 on openSUSE and the possibility of installing it from an unsupported repository, see http://en.opensuse.org/KDE3 .

• Strigi/Nepomuk

  The Strigi indexing service and Nepomuk semantic desktop service are not enabled by default in KDE in openSUSE 11.2. To explicitly enable them go to KDE configuration (applications menu, 'Configure desktop'), the 'Advanced' tab, and in the 'Desktop Search' configuration module enable the services you wish to run.

Thunderbird

With openSUSE 11.2 we ship Thunderbird 3.0 beta4, which will go final shortly after the 11.2 release.

If you still depend on add-ons, which are only available for Thunderbird 2.0, you can install this version from the mozilla buildservice repostitory at http://download.opensuse.org. But note, Thunderbird 2.0 will be only supported for very short period of time, once version 3.0 is available.

System Upgrade with zypper

If you update with zypper dup, packages might get restarted during the update process. It can happen that the restart does not succeed before you adjust the config files. This is especially critical if your system relies on services needed for downloading the update packages, e.g. a local proxy (squid) on the machine you update.

Set commit.downloadMode = DownloadInAdvance in /etc/zypp/zypp.conf so that everything is downloaded first, before the packages get installed. The download transaction needs a huge amount of space on the /var partition to store all the software packages.

Starting the OpenSSH SSH Daemon (sshd)

The OpenSSH SSH daemon (sshd) is the daemon program for ssh. It is no longer started by default at system boot. If you want to access your computer with ssh, you must enable it as follows:

1. Start YaST and open the runlevel editor (System > System Services (Runlevel)).

2. In the YaST runlevel editor enable Expert Mode and select sshd.

3. For example, enable it for runlevel 3 and 5. Then press Start and OK.

Nieuwe backend voor de Samba wachtwoordconfiguratie: tdbsam

Nieuwe backend voor de Samba wachtwoordconfiguratie is tdbsam. Voorgaande Samba pakketten meegeleverd met openSUSE 11.1 en eerder gebruiikten smbpasswd als de syandaard passdb backend. Het was niet expliciet ingesteld in het meegeleverde /etc/samba/smb.conf configuratiebestand. Met deze openSUSE uitgave worden twee wijzigingen geïntroduceerd:

• De nieuwe standaard meegekomen met de broncode en, indien niet op een andere manier ingesteld, met tdbsam.

• De nieuwe standaard is ook expliciet ingesteld in smb.conf.

Als u smb.conf in openSUSE 11.1 of eerder hebt gewijzigd, dan zal het opwaardeerproces smb.conf.rpmnew installeren en uw oude configuratie bewaren.

Controleer in het oude configuratiebestand of passdb backend was ingesteld. Zo niet, dan zijn er twee mogelijkheden om Samba weer te laten draaien:

• Converteer smbpasswd naar tdbsam (aanbevolen!); voer als root in op de commandoregel:

  pdbedit -i smbpasswd:/etc/samba/smbpasswd -e tdbsam:/etc/samba/passdb.tdb
  

  En verzeker u ervan dat de globale sectie van smb.conf zo'n item heeft:

  passdb backend = tdbsam

• Stel passdb backend = smbpasswd in

Wij raden ten zeerste aan de nieuwe standaard tdbsam te gebruiken. Gebruik de oude backend alleen als daar een absolute noodzaak voor is. In dat geval, ga na of u een bugrapport zou moeten indienen zoals is gesuggereerd in http://nl.openSUSE.org/Samba in de sectie "Samba bugrapporteren en geavanceerde debugginginformatie".

Instellen van passdb backend = smbpasswd maakt het u mogelijk om bij de oude configuratie te blijven.

Bedenk dat het oude hulpmiddel een kleinere set functies leverde dan de nieuwe standaard wachtwoordconfiguratie-backend tdbsam.

MySQL 5.1

MySQL version 5.1 is available. Some changes are not backward compatible. The most important are:

• The MySQL socket is moved to /var/run/mysql.

• The Berkley DB storage engine is no longer available.

• Some storage engines are now shipped as modules. You must remove the skip-federated option in /etc/my.cnf, if you upgrade from a previous openSUSE versions.

For more information, see http://en.opensuse.org/MySQL-5.1 and README.SuSE shipped with the MySQL package.

Nieuwe standaard aankoppeloptie: relatime

De kernel koppelt bestandssystemen nu standaard aan met de relatime optie en werkt de inode toegangstijden bij relatief tot de modificatie- of wijzigingstijd. Dit heeft speciaal voordeel op een bureaubladsysteem.

Als u het voorgaande gedrag terug wilt, dan stelt u de strictatime optie in met het YaST partitioneringsprogramma of direct in /etc/fstab.
