openSUSE 11.2發行紀事

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.

E-Books 型式的 openSUSE 文件 (EPUB)

除了傳統的 PDF 和 HTML 輸出格式， openSUSE 系統文件現在提供 EPUB 的 e-books 格式。 EPUB (electronic publication) 是免費且開放的 e-book 標準。關於更多 EPUB 資訊，請參閱 http://en.wikipedia.org/wiki/EPUB.

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.

新的 Samba 密碼設定後端： tdbsam

新的 Samba 密碼設定後端為 tdbsam。 openSUSE 11.1 或之前版本搭載的 Samba 套件使用 smbpasswd 做為預設的 passdb backend。它並未明確的在搭載的 /etc/samba/smb.conf 設定檔中設定。使用此 openSUSE 發行版引進了兩個變更：

• 在原始碼中預設繼承的(如果未做其他設定)為tdbsam。

• 此新的預設值也會明確的在 smb.conf 中設定。

如果您在 openSUSE 11.1 或更早版本已修改了 smb.conf。更新程序將安裝 smb.conf.rpmnew 並保有您的舊有設定。

檢查舊的設定檔，查看 passdb backend是否已設定。如果沒有，有下列兩種可能可讓您的 Samba 再次運行：

• 轉換 smbpasswd 到 tdbsam(推薦！);以 root 在命令行：

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

  然後確認在 smb.conf 的 global 區段有這樣的內容：

  passdb backend = tdbsam

• 設定 passdb backend = smbpasswd

我們強烈建議您使用新的預設 tdbsam。只有在您絕對需要時才保留舊的後端。 如果發生此狀況，您可以到 http://en.openSUSE.org/Samba 回報錯誤，使用 "Samba bug reporting and advanced debugging information" 區段。

設定 passdb backend = smbpasswd 允許您停留在舊有的設定。

請牢記在心，新的預設密碼設定後端 tdbsam，提供了比舊有工具更多的功能。

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.

新的預設掛載選項： relatime

現在核心掛載檔案系統預設使用 relatime 的選項，所以更新 inode 存取時間會和修改或變更時間相關。這尤其對桌面系統是一個進步。

如果您想要保留舊有的行為，使用 YaST 分割程式或直接在 /etc/fstab 設定 strictatime 的選項。
