	DESY Linux 5 Release Notes

Mission

The mission of DESY Linux 5 development is provide a modern, flexible, stable, maintainable, all purpose Linux for use at DESY. This includes support for every server and desktop hardware which follows established DESY Standards as we had in previous releases, plus extended support and reduced network dependencies for autonomous computers in control or mobile applications.

Base Distribution and Tools

DESY Linux 5 is based on the SuSE 8.2 Professional distribution. SuSE's commitment is to support this distribution with bug fixes and security updates until at least April 2005.

We will be using in house mechanisms (AMS, wboom, QIP, YP) for PC registration and creation of installation prerequisites. An automated, slim base installation will be performed by SuSE's YaST 2 and steered by our configuration management tools. DESY (Hamburg) customisation (cluster, group and host specific), post installation, maintenance and administration will be done by a combination of our in hose tools AMS, wboom and salad.

Target Hardware

DESY Linux 5 is supposed to run on

DESY Standard PCs with a minimum of 128 MB RAM and 8 GB IDE hard disk, i.e. every standard PC since mid 1999 or equivalent hardware.
Single and dual CPU server systems with a minimum of 128 MB RAM and 8 GB IDE or SCSI disk drives, including 3ware IDE RAID arrays.
Selected Notebooks (to be defined)

Parameters and Settings

DESY Linux 5 will come with Linux Kernel 2.4.24 or higher
AFS system type is 'i586_linux24'
AFS version is OpenAFS 1.2.10 or higher
glibc is version 2.3.2 as in SuSE 8.2
gcc is version 3.3.1 supplied by DESY

Default partioning for desktop systems is

/dev/hda1    /         6000 MB
/dev/hda5    swap      1000 MB
/dev/hda6    /afscache 4000 MB
/dev/hda7    /scratch   [rest of the disk]

Repositories

The main repository of DESY Linux 5 resides in AFS on /afs/desy.de/products/linux/dl5/inst. The subdirectory base contains the modified contents of the SuSE DVDs and is mirrored onto the installation server linux.desy.de, from where it can be mounted via NFs on any DESY host on the path /distro/DL5.

Application Software

The application software supply and update scheme has been completely remodeled to aloow local installation of packages and run independently of AFS or network connections. Installed applications are a mix of packages supplied by SuSE in the distribution and DESY add on RPMs supllied by the DESY -IT-.
