1 CD Install allows you to install either a basic SUSE-standard kde minimal or gnome system on 1 CD and also a SLICK modified version. Both versions can be updated using YOU. Slick can also be updated to bleeding edge code using kynaptic/apt. Additional software for standard can be installed by using the public yast repositories or the DVD version. Additional software for modified (SLICK) can also be installed by using the public yast repositories or the DVD version or by using kynaptic, which is the prefered way for SLICK. A 1 CD install is just a base to access all the SUSE packages and more.

  • 13.10.2005: The whole openSUSE and apt network is currently overloaded. The big demand of the 5 ISO's of SUSE and Updates available under Susewatcher Yast Online Updates and the 1 CD installer has brought our mirror network on its knees. They are currently only reporting either very slow or even as failed TCP connections. We are all working on it as fast as the different time zones sometimes allow.

What is SUPER?

SUPER is a testbed for anything that makes your SUSE Linux OS perform in a different manner than intended in the more stable and enterprise oriented SUSE Linux tree. This can be a speed improvement geared towards the specialised desktop user or an additional feature that is considered too experimental or dangerous by the main SUSE Linux tree.


The SUPER project concentrates on creating packages and modifications to SUSE Linux in the following areas:

  • Speed
  • Graphical Attractiveness
  • Missing features
  • General Experiments, bleeding edge.

Do you want to help? Let us know by subscribing to the opensuse-optimize mailinglist. The following information is probably going to change heavily once more people have input into it.

Subprojects

This is an openSUSE user driven project.

This project is done by members of the openSUSE community.

We do not want to create a new distro out of this or a fork that requires large amounts of code maintenance, since that would be futile. We only want to add certain packages and features that for one reason or another are not available in the standard SUSE. This can be interesting for both the demanding geek and the power hungry desktop user alike.

Current Project Members

Please add yourself if you contribute.

Technical Details

Currently to be integrated enhancements

  • Prelinking
  • preload kde+OpenOffice (has now been integrated into SUSE beta4 standard, thanks a lot suse.de folks, you rock!)
  • Con Kolivas kernel patches (will not be used unless we have someone with kernel skills on board)
  • Some i686 packages ( binutils preload gcc bzip2 zlib arts bash fam fontconfig freetype2 gdbm gimp glib2 gzip jpeg libpng MozillaFirefox openssh openssl prelink sysvinit tar util-linux xorg-x11)
  • Fonts Optimal Use of Fonts on SuSE
  • reiserfs noatime,notail
  • Security enhanced (no root logins)
  • Test also with defragmented filesystem
  • test with XFS noatime,nodiratime,logbufs=8 + mkfs.xfs -d agcount=45 -l size=64m

The howto is based on beta2 and is available on 10.0 beta2 i686 SUPER and the repository is on [3]. As soon as the super modified iso is released the mods become maintained and we can move on finding more mods.

Kernel -ck patch notice

New kernel rpm's with CK integrated under:

packages


I'm currently running SUSE RC1 with the ck patchset, and am experiencing computing excellence.

Linux linux 2.6.13-ck5-8-default #1 Mon Sep 19 07:51:00 EDT 2005 i686 i686 i386 GNU/Linux

These patches have been made by Con Kolivas:

[ http://ck.kolivas.org/patches/2.6/2.6.13/ ]

There is a patch for RC1 (8) and opensuse final (15) kernels.

For serious audio/music computing jackd must be used with realtime privileges - without root login. The kernel requires the realtime kernel module, which can be acquired from sourceforge.net - use search. The realtime module module cannot be loaded to the kernel without compiling two important things into the kernel: 1. Processor Type and Features --> CONFIG_PREEMPT=y CONFIG_PREEMPT_BKL=y 2. Security options --> CONFIG_SECURITY_CAPABILITIES=m

The realtime module must be loaded as root with parameter "any=1" (modprobe realtime any=1) before starting for example qjackctl. Jackd without realtime capabilities reaches latencies barely < 40 ms , with realtime module latency < 10 ms. is a piece of cake.

Binary drivers Notice

Got 2 rpm's for you to test. You need kernel‑sources and gcc and make: http://opensuse.linux.co.nz/apt/suser-agirardet/10.0/RPMS/i686/nvidia-7676-1.SUPER.i686.rpm http://opensuse.linux.co.nz/apt/suser-agirardet/10.0/RPMS/i686/fglrx-8.16.20-1.SUPER.i686.rpm

ATI driver:

# rpm ‑Uvh  fglrx‑8.16.20‑1.SUPER.i686.rpm 

then run the following on a konsole

# sax2 ‑r ‑m 0=fglrx ‑b /usr/share/doc/packages/fglrx/sax2‑profile


Close, Test and Save the new configuration and exit sax2 and restart X

NVIDIA driver:

# rpm ‑Uvh nvidia‑7676‑1.SUPER.i686.rpm

Restart X

A few technical principles we follow

  1. Create SUSE addon packages that make it fast and snappy and contain experimental features not found in the standard more consumer/enterprise oriented and stable SUSE. SUPER can be your testbed for things to come and features you want to try and keep in a maintained manner until they could if accepted go into the mainstream code base or be maintained within SUPER.
  2. Create test reports on features/speed improvements that then could be going into the mainstream branch. These reports are geared to prove to the mainstream maintainers to take this feature/improvement on.
  3. We should stay as close as possible to the SUSE Linux code, since this means that each openSUSE release gets followed on the day by our "addon" packages. Those packages should and could be installed on top of an existing SUSE install or for convenience sake we could also create a 1 CD/DVD desktop distro a user can download and install quickly and then install additional packages onto with Yast or Kynaptic/Synaptic against the gwdg.de or other repositories. We could also create a mini install containing <150 base packages on top of which a geek can install the rest. The result is a fast and experimental SUSE in which new technologies that improve speed and performance in any way can be tested and then used in a maintained manner with the SUPER repository.
  4. Create scripts to be able to release the modifications on the day of a new SUSE Linux release or of a development release or of an updated package.


Specific areas of interest to openSUSE users

Speed

  • recompile in the following order (some packs might not exist, since I took these from my previous experience with another distro).

binutils preload gcc bzip2 zlib arts bash fam fontconfig freetype2 gdbm gimp glib2 gzip jpeg libpng MozillaFirefox openssh openssl prelink sysvinit tar util-linux xorg-x11


  • Look at if it is possible to the packages we decide should be optimised as athlon and pentium4 optimised packages and not just i686 on a DVD edition and have the installer choose according to that architecture. That would be the ideal scenario
  • create base install (150 packages)
  • add apt to it
  • add prelink
  • apt-get install kdebase and add some more packages to make it all look good.
  • add some yast packages
  • get the file list
  • compile kynaptic and add it
  • autoyast instruction. Easy install for dummies
  • Test, test and create a objective comparison system
  • Compare to standard SUSE Linux and create chart.
  • Publish results and get more people onboard.
  • The whole build process should be scripted so that we can just run the script when a new opensuse comes out.
  • Consider adding some lightweight X window managers e.g. blackbox, fluxbox or icewm


Boot optimisation

  • initng
  • reduce file operations esp during boot. Can get achieve by different configuration or changing applications.
  • Cache files for bootup with readahead. Note: Suse is already working on this! Have a look at their new preload package version 0.2, included with beta3

A hint from a user that contacted me offlist from the openSUSE project brought me to look at readahead, which is used by Fedora. In the bugreport there is a perl script to extract that information and create all the needed readahead files. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=128444 Script is attached at https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=113401

Graphical Attractiveness

  • 3D graphicsdrivers included for ATI and NVIDIA (or at least as easy install by YOU for ATI drivers than Nvidia)
  • Optimal Use of Fonts on SuSE

Missing Features

This section will contain software that is missing from SUSE. Some of the software is hosted in countries where the distribution of the code is allowed. This is valid for the DVD, media and other code.

  • MPLayer fully featured
  • kaffeine fully featured
  • mp3 fully integrated
  • Xserver. Use a tiny and fast Xserver as experimental feature
  • SLICK create a very slick iso for those who like it minimalistic.
  • Repositories and easy upload policy as discussed on the opensuse-optimize list
  • Java
  • rar
  • Azureus


Current Issues

  • more people needed to actively pursue tasks and find areas of potential optimisation
  • Online reiserfs defragmentation tool needs to be written
  • Reiserfs4 needs to be integrated into the yast installer

.


Unsorted ideas

  • First test hack to prove that it can be done and is useful and get more people onboard.
  • Webbased userfriendly packages delivery SUPER_KLIK.
  • Harden OpenSuse with Bastille Linux, or provide this option at install. Need to assess impact on speed/performance, if any.
