openSUSE 10.2 Release Notes

Copyright© 2006 Novell, Inc.

The release notes are under constant development. Download the newest version during the Internet test or refer to http://www.suse.com/relnotes/i386/SUSE-Linux/10.1.1/RELEASE-NOTES.en.html.

These release notes cover the following areas:

  • General: Information that everybody should read.

  • Update: Changes that are not mentioned in the Start-Up Manual, Chapter 2.

  • Technical: This section contains a number of technical changes and enhancements for the experienced user.

In the Start-Up Manual, find information about installation and basic system configuration. In the Reference Guide, the system configuration is explained in detail. Additionally, the most important applications are described in the GNOME and KDE User Guide.

General

New Software Management Tools: zypper and opensuseupdater

10.2 also introduces a new set of light-weight software management tools to be used even without the ZENWorks Management Deamon (ZMD) running:

  • The zypper command line tool is software managment tool. Besides managing updates as offered from the update server it can also install or deinstall regular packages. Find more information in the zypper man page.

  • The opensuseupdater is a desktop applet that helps you monitoring available software updates and install them easily or automatically, if wanted.

Changes with Firefox 2

Switch from Firefox version 1.5 to version 2 is a major update. Find detailed update information in the official release notes at http://www.mozilla.com/en-US/firefox/2.0/releasenotes/. Note the following changes:

  • Some themes and extensions from Firefox 1.5 will not work with Firefox 2.0 anymore and need to be updated.

  • Default keybindings are changed. For example, backspace does no longer take you back in history, it will now scroll up the page. You can change it by opening the location about:config. The value of the configuration key browser.backspace_action needs to be changed from 1 (default) to 0.

New wodim Package to Write Optical Disk Media (CD-ROM/DVD)

The "cdrecord" package has been dropped from the distribution. The new "wodim" package can be used to record data or audio Compact Discs on an Orange Book CD recorder or to write DVD media on a DVD recorder.

Alternatively use "growisofs" for writing DVDs. The graphical front-ends handle this transparently.

The OpenSync Synchronization Framework

For synchronizing mobile device the OpenSync suite replaces multisync. For more information, read the "Mobility" part of the Reference manual.

Add-On Medium with Additional Languages

Include the language add-on medium in your list of installation sources, if you want better support for one of our tier 2 languages. Tier 2 languages are all but the tier 1 languages (English, French, German, Italian, Spanish, Brazilian Portuguese, simplified and traditional Chinese, Japanese, and Czech). Support for tier 1 languages is available on the standard media set.

Update

Configuration of CUPS (Common UNIX Printing System)

The update of CUPS from version 1.1 to 1.2 carries incompatible changes. It is not possible to convert the printer configuration from the previous CUPS versions automatically. Use the YaST printer setup ("Hardware" -> "Printer") to reconfigure the printing system.

For reference, check the save configuration files:

/etc/cups/classes.conf.rpmsave

/etc/cups/printers.conf.rpmsave

Technical

The Standard Kernel

The kernel-default package contains the standard kernel for both uniprocessor and multiprocessor systems. The kernel comes with SMP support and runs with only minimal overhead on uniprocessor systems. There is no kernel-smp package anymore.

The New Default File System: ext3

The YaST partitioner now defaults to create new file systems using the ext3 type replacing reiserfs. The ext3 file system is known for its backward compatibility with the ext2 file system.

The high performance directory hashing option is enabled by default. This feature uses hashed b-trees to locate directory entries. By not requiring the entire directory to be read, this accelerates lookups in large directories dramatically. Although it is not recommended, the administrator can disable this feature by removing the "dir_index" option in the YaST partitioner.

Setting Up LVM and EVMS with YaST

Experts can now rely on YaST for configuring LVM (Logical Volume Manager) and EVMS (Enterprise Volume Management). Find detailed information in the Reference manual, Chapter "Advanced Disk Setup".

SMART Disk Monitoring Daemon (smartd)

The SMART Disk Monitoring Daemon (smartd) now also supports SATA hard disks without the "-d ata" switch. Status notification happens via powersavenotify. smartd is not enabled by default. To enable it, start the YaST runlevel editor ("System" -> "System Services (Runlevel)") and check smartd service.

For more information, see the smartd man page.

BIOS RAID Supported During Installation

BIOS RAID is now supported during installation. Activate it in the BIOS and run a default installation.

X.Org Specific Changes for Developers

The X.Org system is installed in /usr. Adjust your programs if needed. If you are referencing fonts by directory names like XEP, find the new directories now in /usr/share/fonts.

New Power Management Options

The suspend framework switched from powersavedpm-utils. This switch makes many configuration options in /etc/powersave/sleep obsolete. Instead configure suspend in /etc/pm/config now. For more information, refer to http://en.opensuse.org/Pm-utils.

Security Leftovers

  • Someone is putting lots of work into hacking Github developers [Ed: Dan Goodin doesn't know that everything is under attack and cracking attempts just about all the time?]
    Open-source developers who use Github are in the cross-hairs of advanced malware that has steal passwords, download sensitive files, take screenshots, and self-destruct when necessary.
  • Security Orchestration and Incident Response
    Technology continues to advance, and this is all a changing target. Eventually, computers will become intelligent enough to replace people at real-time incident response. My guess, though, is that computers are not going to get there by collecting enough data to be certain. More likely, they'll develop the ability to exhibit understanding and operate in a world of uncertainty. That's a much harder goal. Yes, today, this is all science fiction. But it's not stupid science fiction, and it might become reality during the lifetimes of our children. Until then, we need people in the loop. Orchestration is a way to achieve that.

Leftover: Development (Linux)

  • Swan: Better Linux on Windows
    If you are a Linux user that has to use Windows — or even a Windows user that needs some Linux support — Cygwin has long been a great tool for getting things done. It provides a nearly complete Linux toolset. It also provides almost the entire Linux API, so that anything it doesn’t supply can probably be built from source. You can even write code on Windows, compile and test it and (usually) port it over to Linux painlessly.
  • Lint for Shell Scripters
    It used to be one of the joys of writing embedded software was never having to deploy shell scripts. But now with platforms like the Raspberry Pi becoming very common, Linux shell scripts can be a big part of a system–even the whole system, in some cases. How do you know your shell script is error-free before you deploy it? Of course, nothing can catch all errors, but you might try ShellCheck.
  • Android: Enabling mainline graphics
    Android uses the HWC API to communicate with graphics hardware. This API is not supported on the mainline Linux graphics stack, but by using drm_hwcomposer as a shim it now is. The HWC (Hardware Composer) API is used by SurfaceFlinger for compositing layers to the screen. The HWC abstracts objects such as overlays and 2D blitters and helps offload some work that would normally be done with OpenGL. SurfaceFlinger on the other hand accepts buffers from multiple sources, composites them, and sends them to the display.
  • Collabora's Devs Make Android's HWC API Work in Mainline Linux Graphics Stack
    Collabora's Mark Filion informs Softpedia today about the latest work done by various Collabora developers in collaboration with Google's ChromeOS team to enable mainline graphics on Android. The latest blog post published by Collabora's Robert Foss reveals the fact that both team managed to develop a shim called drm_hwcomposer, which should enable Android's HWC (Hardware Composer) API to communicate with the graphics hardware, including Android 7.0's version 2 HWC API.
