What is CERN E. Linux ?

CERN assembled Linux distribution

Recompiled from sources of Red Hat Enterprise	Linux 3 (AS/ES/WS)

Customized to integrate in the CERN Computing Environment

Added / changed software

Possible long-term support product

Subject to CERN-wide discussion (and funding !) ...

CERN Customization(s)

All components recompiled from RHEL sources are included (Red Hat did not ship some ...)

Some components customized:

Kernel with added set of patches (not yet ..)

Some configuration 'wizards' changed (..)

Some products are updated

Mozilla 1.5 (instead of 1.4) - From Fedora Core 1

OpenOffice 1.1 (instead of 1.0) - From Fedora Core 1

CERN Customization(s)

Added software

Openafs, Heimdal Kerberos 5, Kerberos 4, CASTOR client, pine ...

Red Hat software update mechanism replaced

Red Hat up2date cannot be used (server-side – Red Hat Network is RH proprietary)

Legal issues

Source of all software included is under GPL or other free license (MIT, BSD .... etc...)

Freely available from ftp.redhat.com

Red Hat EULA for RHEL 3 says:

Binaries obtained from Red Hat cannot be freely redistributed.

Red Hat logo and trademarks cannot be used without permission

Trademark Policy should be respected

“Title to the Software and any component, or to any copy, modification, or merged portion shall remain with the aforementioned, subject to the applicable license”.

And ... there are others: Fermi LTS 3.0.1, WhiteBox Linux, Caos Linux ....

Red Hat Compatibility

It is the goal !

Fermi LTS 301 / Whitebox ... others:

ALL should be binary compatible

If NOT -> Tell us ... it is a bug ... not feature ...

Binary-only products compiled for RHEL 3 AS/ES/WS should run

Maybe after some tweaking of /etc/redhat-release

But without support ....
