h1. Autoyast based unattended installation

h2. Media notes

Installation media can be accessed via nfs,ftp or http. The path to the installation media differs from SLES9 and SLES10/11. So you have to create two separate installation media entries in foreman.

h3. SLES9

ftp://server/SLES/$major.$minor_$arch

h3. SLES10/11

ftp://server/SLES/$major.$minor_$arch/CD1

h2. Autoyast files

The Yast2 provisioning templates provided by foreman are working fine for OpenSUSE but not really for SLES. The version of puppet is way to old even on SLES 11.1. One way to install a more recent version is to download a patch from Novell's website. The patch can be put on a additional installation source and included in the installation process. 

h2. Puppet Patch

h3. SLES 11

Download the patch from Novell's website. Please note that you need a valid support contract to download the patch. Create a minimal installation source that can be added during the installation process. This will ensure that a later version of puppet is installed during deployment with foreman. You can find very good instructions on how to create an installation source here:

A good and minimal provisioning template tested on SLES 11.1:
